Kenwood DP-R5060 5-Disc CD Player

I’ve just listed this cool Kenwood DP-R5060 5-disc CD player. This is a multi-disc machine and not as nice as the Yamaha player listed elsewhere in the store, but still a good machine, perfect for a second system or to replace a dead multi-disc machine.

This Kenwood DP-R5060 5-disc player is just $195.

Classic BIC Venturi Formula 4 Three-Way Speakers

Wow, look at this classic pair of legendary BIC Venturi Formula 4 three-way speakers, made in the US of A and just in. Feel the power of the Venturi!

The BIC Venturi Formula 4 is a classic and well-regarded large three-way bookshelf style speaker from around 1975. These were quite famous back in the day, you can read more about them here.


Power Handling:  100 watts RMS
Frequency Response:  25 – 23,000 Hz
Dispersal:  120° x 120°
Impedance:  6 Ω nominal
Woofer:  10″
Midrange:  Biconex
Treble:  Super Tweeter
Controls:  Manual and Automatic Dynamic Tonal Balance Compensation
Grille:  Reticulated, zero-loss removable foam.
Colour:  Brown, Black, Beige, Burnt Orange, Blue, Red
Dimensions (W x H x D):  13 ¼” x 25′ x 13″
Weight (shipping):  48 lbs


Genuine three-ways aren’t a common thing, and desirable for a number of good reasons. A three-way design allows greater tailoring of drivers to suit a narrower band, very useful to improve power handling and reduce distortion.

This pair of BIC Venturi Formula 4 speakers are in excellent condition for their age. The original foam grilles have long since decomposed and been replaced with this quite stylish grille cloth which I prefer. Other work may have been done behind the grilles, but since these are now semi-fixed, I can’t say for sure. All drivers appear original though, from what I can see.

I cleaned and tested this pair and replaced the nasty, broken factory speaker terminals with some much more substantial gold plated banana terminals. I also replaced one of the attenuator fastener nuts.
These gold plated banana terminals are much better than the originals.
There’s a little veneer-lift in places, but nothing that can’t be fixed with a little glue and 5 or 10 minutes!

These BIC Venturi Formula 4 speakers have a lot of bass for their size, it’s actually quite surprising on first listen. This was part of their appeal and meant that a high dynamic range was possible, even with smaller systems. Mids and highs are clean and the horn does a great job of increasing sensitivity and adding to that punch that horn drivers deliver.

These iconic speakers need a new home and I don’t have room to store them so they are priced to sell at $495.

Chipamp LM4780 Deluxe Dual-Mono Amplifier Kit, NOS, Genuine Audiosector Kit!

Many of you will have seen my LM3886 gainclone amplifier build and know how great that amplifier sounds. It is also for sale, here very soon. But here we have another kit from the same great vendor, Peter Daniel, who operates Audiosector and is famous for these kits and amplifiers.

This is the LM4780 parallel kit, the highest power, highest-fidelity option available, with each LM4780 running in parallel, creating a 120 Watt per channel dual-mono hi-fi stereo amplifier. The LM4780 is two LM3886 dies in one package, the idea being to increase current capability and power output.

I wrote about my plans for the amplifier in this article, but never got around to building it!

These kits are extremely high quality, with premium parts, thick boards, gold plated traces. They are the complete opposite of the kits you’ll find on eBay filled with fake parts from China. I really rate these which is of course why I bought it. I never got around to building it though and it needs to go to a new home.

For those wondering the dual-mono LM4780 has more than twice the 40 – 50 Watts per channel produced by the LM3886. This one also comes complete with the heavy-duty, high capacity power supply capacitor option of 4 x 22 000uF capacitors.

To complete the kit, you can refer to Peter’s site, to the circuit diagrams that come with it and you’ll also need a suitable transformer, or transformers, depending on how you want to complete the kit and how far you want to take it. This is a premium kit with all genuine parts from the best vendors.

The LM4780 dual-mono chip amp kit, with the high capacitance upgrade and all the extras, is around $200 landed. I’m looking for something close to that for this complete and unused premium kit, let’s say $150.

Legendary Pioneer A-400 Integrated Amplifier, One of the Best!

Alright, so many of you will know about this legendary classic integrated amplifier from Pioneer – the A-400. One of the best-reviewed amplifiers of its era, this little gem is still widely used in many good systems.

The Pioneer A-400 hails from the early ’90s. She features 50 Watts per channel, solid build and a focus on sonic performance over features, hence the low switch and control count. More can be found here, including the very high review ratings.

This one is cosmetically and electrically perfect – EXCEPT – check out the back panel connectors. I have no idea what happened here, I don’t really care either. I’m not fixing it but someone else certainly can if they can be bothered.

Nope, I have no idea what happened here but my best guess and what almost always causes it is stupid cables. What are stupid cables? Typically ’boutique’, ridiculously heavy cables that often have those locking-style RCA connectors on the ends. The speaker terminals are damaged as well. I won’t be fixing this but someone can!

Other than this back panel madness, the amplifier works perfectly. A good project for someone I reckon.

Grab this lovely old girl, in need of a little TLC, for $150.

Wow – Music Angel XD-845 Mk3 Class-A Tube Amplifier, Cosmetically Imperfect, NOS!

Check out this beautiful Music Angel XD-845 Mk3 class-A single-ended triode tube amplifier for sale. This is a cosmetically imperfect unit and sold as-is, without tubes, but I have no reason to believe there is anything wrong with it, other than some cosmetic damage.

I sold the replacement unit many years ago, you can see and read about it in this article. Since then, this original, shipping damaged unit has been sitting in a box, unused, waiting for me to do something with it! Well now is that time.

The Music Angel Class-A 845 is a beast. This is 28kg of pure Class-A, single-ended triode (SET) tube amplifier that sounds nothing like any solid-state amplifier you’ve ever heard. The 845 is warm, liquid-smooth and powerful for its rated 20 Watt/ch rating.

With an amplifier like this, you’ll hear mid-range magic that only SET amps provide. The 845 also has prodigious bass and you get to look at those gorgeous output tubes glowing orange, with the lights out…

There is a ton of info out there on these liquid-smooth sounding tube amplifiers, so just search for Music Angel 845 and loads of articles will come up. This unit obviously has no tubes and is priced accordingly.

Signs of damage here, this could of course easily be repaired, but I’ve left it as is.
More signs of damage here. It’s cosmetic stuff and the ambitious could sort this out.

As mentioned, I don’t have any original PSVane tubes for this unit. I DO have some very nice NOS Russian military small signal tubes though and potential owners are welcome to hit me up about those. A set of four will set you back $100. The big 845 output tubes can be purchased from around $150 per set of two, prices go up from there. So you need say $300 worth of tubes and she is cosmetically imperfect but otherwise good.

This otherwise lovely, NOS, Music Angel XD-845 Mk3 Class-A amplifier comes in her original box and sold for around $1500 AUD new, in 2014.

She is sold as-is, needing tubes, a great and almost complete project for someone. I have sets of the four small signal tubes available as mentioned. Make me a sensible offer!

Attention Yamaha Speaker Lovers

Uber-Rare Set of Two Genuine NOS Yamaha NS-1200 / JA3120 Woofer Re-Cone Kits!

These NEVER, EVER come up.

Yes, this is likely the only set of two genuine Yamaha NS-1200 JA3120 woofer re-cone kits left. IN THE WORLD!

I have too much NOS stuff and as long as I don’t own NS1200s, I need to move these kits on. I realise that as soon as I sell them I’ll find a pair, but that’s too bad.

JA3120 re-cone kit

Yamaha NS-1200 JA3120 re-cone kit
I know what you’re wondering: “Mike, how do you even own these?” Long story but look at these pristine beauties!

If you own NS-1200s and want to re-cone your JA3120 woofers, the only way to do it properly is with genuine parts like these. The woofers won’t retain their Theile-Small characteristics unless you use genuine parts.

This pair of re-cone kits will repair damaged spiders, voice coils and surrounds. These genuine Yamaha parts come in factory original boxes and include cones, surrounds, voice coils, spiders and braids. The original boxes retain all of their foam support material, so shipping should be perfectly safe.

Yamaha NS-1200 JA3120 re-cone kit
All Yamaha, all original, stupid-rare!
Yamaha NS-1200 JA3120 re-cone kit
And yes, this is a set of two of these re-cone kits, in genuine packaging.

These are in perfect, unused, original condition. Shipping anywhere, at cost. Sold as-is, these are NOS spare parts, no warranty.

Keep in mind there will likely never be another pair of these for sale.

Serious offers entertained, get in touch to discuss.

Lovely Yamaha CDC-705 Multi-Disc CD Player

Here is yet another beautiful CD player from back in the day. This CDC-705 was one of the best Yamaha five-disc machines, with impressive weight and build for this style of machine.

Recently serviced with a new tray drive belt, clean and lube, this player runs very well and plays discs perfectly. You can read more about the CDC-705 here.

The CDC-705 is also in almost perfect physical condition, amazing given that she hails from 1990!

Need a good multi-disc player, with some classic vintage style and build quality? This classic Yamaha CDC-705 CD player can be yours for just $295, not much at all for such a cool player.

Beautiful Rega Jupiter CD Transport + Solar Remote Control

Take a look at this beauty newly listed for sale. Featuring a top-loading Sony transport and Rega’s minimalist design aesthetic, the Rega Jupiter has to be one of the coolest CD transports from the heyday of the compact disc. This is truly a cool CD transport, just begging for a really nice DAC to go with it.

The Rega Jupiter is a CD transport only, with coaxial digital out, meaning you’ll need a DAC. Rega planned for you to buy their Io DAC, but any good DAC will work well with this transport, be it in a receiver, streamer, or a dedicated standalone DAC.

So why a transport? Well, a CD transport isolates the mechanical and RF aspects of disc playback from the sensitive analog circuits found in the DAC. This ultimate separation of duties allows for the very best sound quality. It’s the way I do things for CD playback in my own system for example.

The Rega Jupiter is a well-regarded transport from one of the big names in British hi-fi. You can read some real reviews from owners here. I love the minimalist design and red LED display. The top-loading drive is a very nice touch. You simply load a disc and let the lid slowly drop onto the disc, clamping it in place and activating the drive.

Freshly cleaned and serviced, this Rega Jupiter also comes with the original owners manual and a pristine Solar remote control. The Solar is a Rega system remote that operates a whole slew of their gear from this era. It’s a super useful thing to have if you already own a Rega system, and collectible now in its own right.

Try to find a single mark on this Solar remote control!

This machine had just one original owner before she came into my possession and is a beautiful example of this now rare CD transport.

This rare Rega Jupiter CD transport and Solar remote can be yours for just $500.

Rotel RTC-970 Processor/Tuner/Preamplifier

Also newly listed, this lovely Rotel RTC-970 surround sound processor/tuner/preamplifier is perfect for building a stereo or home cinema system around.

This tuner/preamplifier supports five channels, though you can use it as a stereo tuner and preamplifier in almost any system, so it is very flexible. Use it as a tuner, use it as a preamp, or both!

This almost pristine example comes with a new mains plug, original remote control and owner’s manual. Here is the owner’s manual in PDF.

You can own this lovely Rotel tuner/preamplifier for just $295.

Stunning Sony MDS-JA30ES Minidisc Player

The MDS-JA30ES was Sony’s second from the top-of-the-line minidisc player and an absolute beauty.

This unit is from my personal collection and is in as close to pristine condition as you’ll find. I’ve just given her a full mechanical service, new drive belt, cleaned and lubed the loader and replaced several capacitors in the power supply.

Specifications, courtesy HiFi Engine:

Type: Minidisc Player/Recorder
Track System: 2-channel stereo
Optical Pickup: KMS-210A/J-N
Sampling Frequency: 44.1kHz
Frequency Response: 5Hz to 20kHz
Signal to Noise Ratio: 104dB
Analogue Inputs: 125mV (line)
Analogue Outputs: 2.0V (line)
Digital Inputs: coaxial, optical
Digital Outputs: optical
Dimensions: 430 x 125 x 345mm

There is a problem though, this MDS-JA30ES no longer reliably reads discs. This is a common problem amongst Sony mini-disc players of this era. Sometimes she reads and plays a disc perfectly, other times not.

It most likely just needs a new laser. These are hard to come by and sadly this means that this stunning machine is sold for parts or project work only. She also comes with a pristine remote control. Offers welcome on this one!

Raytheon  JAN 5703WB ‘Trivistor’ Vacuum Tubes

Many will have seen my articles and videos on the iconic Musical Fidelity Tri-Vista 21 Tube DAC. If you need a set of 5703WB vacuum tubes for yours, look no further.

I have 50 – now approx 35  Raytheon 5703WB vacuum tubes available for sale, all from the same production batch. This is the mil-spec, 50+G rated triode tube used in the class-A output buffer of the Tri-Vista 21, Tri-Vista SACD Player, the Tri-Vista 300 Integrated Amplifier and others.

This batch of NOS Joint Arm Navy Raytheon 5703W tubes was made in December 1979 and is a rare find. Good examples like these rarely come up for sale. Many I’ve seen are later examples, in tatty boxes, sometimes even used! Remember, with NOS tubes, the older the better, generally speaking.

All boxes are intact and in excellent to perfect condition. All tubes are NOS, never used, in perfect condition.

Grab a pristine NOS set for your Musical Fidelity Tri-Vista 21 or other project whilst these early date code units are available. Keep them tucked away for when you need them – if you own equipment that uses them, you will eventually need to replace them.

Priced at just $25 AUD per tube. Remember, these NOS tubes are all from the same 12/1979 production batch.

Yes, these are all for sale, I really don’t need so many in stock!
All were manufacrtured in December, 1979.
The boxes are perfect

As are the tube markings. These tubes have never been out of the boxes.
