Amplifiers & Preamplifiers

Classic Harman/Kardon PM650 integrated amplifier

This lovely Harman/Kardon PM650 integrated amplifier was donated to me after her owner, Giles, received advice that she was not worth repairing, or not repairable. I was fairly sure it would be a straightforward repair, especially given where that advice came from, and after a few hours on the bench, she is now running nicely again.

The issue here is that she’s in average cosmetic condition, hence the reduced price. In keeping with the original owner’s wishes, she needs a nice new home. That can happen for $395, sold as is. Thank you, Giles.

This PM650 is certainly one of the nicest-sounding mid-priced integrated amplifiers you’ll find. Featuring a really good, discrete phono preamplifier capable of working with MM and MC cartridges, plus full tone controls, tape loops, and capacity for two sets of speakers, this would make a great upgrade over cheaper entry level amplifiers.

Features

The PM650’s power is conservatively rated. The HCC design means its 50 watts per channel can develop into an instantaneous 200 watts when low speaker impedance demands it. Under heavy loads, when other amplifiers deliver substantially less than rated power, the PM650 delivers substantially more.

The PM650 provides features for serious audiophiles. There are two phono inputs: one for moving magnet cartridges, the other for low-output moving coil cartridges. The MM circuit incorporates a unique capacitance trim, which allows you to precisely match the amplifier to any brand or type of cartridge, assuring absolutely accurate high-frequency response. The moving coil input has its own built-in head amp, so you won’t have to spend more for a separate component.

The PM650 provides loudness contour, tone defeat, mono/stereo/stereo reverse positions, and accommodation for two tape decks and two pairs of speakers. It also features a high-cut filter and two-way tape copy capabilities. In addition, the PM650’s Tape Output selector allows you to record from one source, such as your tuner, while listening to another, such as your turntable.

This Harman/Kardon PM650 integrated amplifier is now available for $395.

Cassette Decks

Stunning Harman/Kardon TD292 Ultrawideband Cassette Deck!

Another generous donation by Aaron Powell, this gorgeous Harman/Kardon TD292 has just been repaired, serviced and is ready to go to a new home.

A real stunner this one, she now has two new belts, cleaned idler and lubed mechanicals, demagnetised and cleaned tape path, and now runs at the correct speed. She now runs and plays perfectly. The only issue is the meters, which work and don’t impact performance, but don’t quite work perfectly.

I’m sure this can be fixed, I’m just not doing it after spending three hours getting her running, but repair will of course be possible. Again, this does not impact tape playback at all!

Another beauty needing a new home. I’ll make no money on this one after the work I’ve done, but we DO save another piece from the scrap heap, and that alone makes this worthwhile. Own her for just $395!

CD Players & DACs

Stunning Rega Jupiter CD Transport + Solar Remote

Take a look at this beauty. I had this listed for a while and received some interstate enquiries, but no local interest, so I rested it for a while. I’ve just cleaned and tested her again, and she still works perfectly. This is far too cool a transport to sit here in storage, so I’m listing her again!

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 pair with.

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? A CD transport isolates the mechanical and RF aspects of disc playback from the sensitive analog circuits found in a DAC. This ultimate separation of duties allows for the very best sound quality. You need to partner her with a really nice DAC, though.

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 serviced, this Rega Jupiter also comes with the original owner’s 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 in its own right.

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

One original owner and a beautiful example of this rare CD transport, this Rega Jupiter and Solar can be yours for just $595.

Miscellaneous

Moth RCM Record Cleaner

This lovely old Moth record cleaner I recently wrote about, is for sale. Just $499!

There are various record cleaning methods, and some are actually useful! Record cleaning is a mildly controversial topic, not because of any inherent complexity; the science is straightforward, but it is often poorly understood and applied. That’s a discussion for another time, but I use dry methods to maintain my clean records, and a couple of wet cleaning methods for records that need it, including an ultrasonic bath, using cleaning fluids that I make.

Before ultrasonic cleaning and various other methods, though, the vacuum-style cleaners were king. The Moth RCM is a classic, if rather noisy, manual machine and packs real record-cleaning punch. The advantage over other non-vacuum wet cleaners is that the suction pulls away cleaning fluid and dirt at the same time, leaving records sparkling clean when used correctly.

The Moth RCM, sold as either a complete finished product or as a kit like you see here, was one of, if not THE most popular, affordable record cleaner available. It’s no Keith Monks cleaner, but when last sold by Decibel Hi-Fi, the ready-made Moth RCM record cleaner cost a cool $1,795 AUD. I believe you can/could still purchase these from the UK, for £595, plus VAT, shipping and other taxes, of course.

Grab this for just $499.

IsoTek EVO3 Genesis One Mains Power Conditioner/Regenerator

Check out this one-owner IsoTek EVO3 Genesis One mains power conditioner, in perfect condition! Which one owner you may ask? Me! I bought it new around 5 years ago and have had zero issues and some nice sonic improvements with connected gear.

A customer asked me what I thought about these and why I’m selling mine. Easy: It’s a great unit, but I need the space and the funds. I’ve recently bought a bunch of expensive Accuphase equipment and various other things, and so a bunch of stuff like this IsoTek mains regenerator must be sold.

In terms of what it does for the sound, it’s a fascinating question. When I first bought this regenerator, I plugged my sources into it and immediately noticed a lower noise floor and a slightly more relaxed sonic presentation from the entire system. I thought this was an interesting and certainly valuable improvement.

If you’ve been thinking of getting one of these, I’d have no hesitation in recommending you do. More importantly, it safeguards your valuable equipment from power surges and spikes, too.

These highly regarded mains power regenerators are the best way to power a source or other low-power devices, far better than a ‘filter’. The Genesis One is a 100 Watt mains voltage regenerator perfect for things like CD players, DACs, preamps, tuners etc. As long as the total power consumption stays under 100 Watts, you are cooking with gas.

Quite different from the common and much cheaper passive filters that you see in all the stores, this is an active device – a power supply – a far better way to power your sources. The Genesis One delivers a rock-steady, regulated 230VAC mains supply with less than 1% distortion. This feeds your sources with the purest, lowest distortion mains supply possible, much cleaner than power straight from the wall.

Contrast this with a filter, a fancy power board with built-in chokes for example, that only reduces line noise. These filters don’t regulate line voltage, nor do they completely regenerate a completely clean and steady 230V sine wave as the Isotek Evo3 Genesis One does.

Here’s some additional info from Isotek:

The EVO3 Genesis One is a state-of-the-art single-cell sine wave generation system with extremely low THD. The system can be used to dramatically improve single front-end components. Each cell can be combined/linked together so that only one input wall socket cable is required.

Removes both Common Mode and Differential Mode mains noise.
Dedicated single outlet delivers clean, low-distortion reconstruction mains sine wave.
Unique single-cell mains sine wave generation system exceeding 85dB of noise reduction extending to zero Hz, running in class D amplification with a linear power supply.
Internal wiring: solid core silver-plated PCOCC with FEP, virtually an air dielectric.
100W of totally clean power for all front-end components.

More information about this award-winning product can be found here.

These beautiful 10kg IsoTek EVO3 Genesis One (try saying that a few times…) mains power conditioners/regenerators are a current IsoTek product and retail for $4,749. You can purchase this perfect, one-owner example for just $1950. How this hasn’t sold yet is beyond me!

NOS 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 30 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 5703WB 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.

Grab a pristine NOS set for your Musical Fidelity Tri-Vista 21 or other projects 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.

All boxes are intact and present in excellent to perfect condition. All tubes are NOS, never used, and in perfect condition. Priced at just $30 AUD per tube.

Receivers

Beautiful JVC JR-S301 AM/FM Stereo Receiver

This gorgeous JVC JR-S301 receiver is ready for a new home and sounds better than ever after a repair involving the replacement of two no-longer-available op-amps. Only one was a problem, but I replaced both with modern high-performance parts and a couple of capacitors, because that’s how I like to do things.

There is an unfortunate backstory to this, but it’s nothing about the equipment itself or the result, both of which are outstanding. I’ll spare readers, but suffice it to say that my pain will be someone else’s gain. I’ve gone beyond the modest pricing of this unit and any margin I had in it, 1) to save it; 2) as an exercise to show how and why we save equipment like this, and 3) to demonstrate why having access to specialists is so important.

This lovely JR-S301 is now one of the nicest-sounding mid-range vintage receivers I’ve heard, significantly better after the work I’ve just completed (August 2025). She is ready to give her next owner many more years of reliable service, hopefully someone who appreciates the equipment and the effort that saved her 🙂

This lovely JVC AM/FM stereo receiver outputs 60 Watts per channel, has lovely VU and tuning meters, four in total, a graphic equaliser, a phono preamplifier, a robust, discrete output stage, JFET input and features a solid build and beautiful appearance. What more could you want in a vintage receiver?!

This receiver is just gorgeous and part of a desirable series of equipment, and quite a rare offering. After a deep clean, service, and repair to the tuning mechanism and tone/buffer amplifier, she works perfectly and has that rich, warm sound people love from equipment like this.
