Stunning Sony MDS-JA30ES Minidisc Player

Recently added for sale, the MDS-JA30ES was Sony’s second from the top of the line minidisc player and an absolute beauty.

for sale

This one 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.

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.

for sale

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 5703WB ‘Trivistor’ Vacuum Tubes

Many of you 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 than these beautiful tubes.

I have 50 – now approx 40  Raytheon 5703WB vacuum tubes available for sale, all from the same production batch. This is the mil-spec 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 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 $20 AUD per tube and remember, these are all NOS tubes from the same 12/1979 production batch.
