Slight pic of the inside below.

"Super cool OG programmable drum machine! Classic 80's vibe. Works! The box has duct tape on the corners to hold it together (before my time) and the battery pack is broken but the white electrical tape does the job. Can also run off a 6v adapter.

Overall in great condition, one of the screws on the backplate is stripped but it's included in the box."

Pics of the inside below.

"Classic 80s 8bit PCM drum machine, used in countless hits.

This particular unit was serviced:

- all electrolytic capacitors were replaced

- switches and pots were cleaned

- latest firmware eprom was installed (3.0)

- factory patterns were loaded

- MIDI interface was added, built using the original E-mu design. This allows you to trigger the 12 sounds over MIDI dynamically

- comes with 4x additional eproms containing the famous LinnDrum LM2 sounds. I made a video a few monthes ago comparing 2 drumulators with stock and linnDrum kit if you want to hear the difference (youtu.be/k_EuRlCi_Vk)

Works perfectly. Cosmetic it is in quite good condition with some scuffs here and there, and also 2 holes were drilled in the back from a previous owner (no idea what was the reason). Unit is 230v."

Oberheim Matrix 12 Repair

"I was lucky enough to be able to restore this amazing instrument.
Hampered at the end by a wrong logic chip installed. From factory? Or 'the last guy'?

R.A. Moog Troubador Theremin #1 a/s

Click the auction link on top when you get there for additional listings.

"***notice that the theremin needs service*** Up for sale is my R.A. Moog Co. Troubador Theremin with serial number 1001. Which means it's the first one made, probably by Bob Moog himself on 3 October 1969. Unfortunately it's not working. One of the coils is broken and the power lead needs work. It's sold as-is, untested. I've been looking years for a second example to fix this one, without result so far.. Optically there are signs of use, some screws are missing, some wear and tear at the front panel and bottom plate."

"Extremely rare, extremely heavy, and not fully functional: here is the fabled Synamp from Moog, interestingly a native UK voltage example. The power amp is not working, and the spring tank needs to be replaced. But this is what it does have working well even before servicing: a vintage Moog graphic with drive level control and overload LED, and four channels of comprehensive Moog parametric EQ, each with input gain with overload LED and effects send level, and three sweepable bands for each channel. Cosmetically, check the photos. The important parts are a good 7/10, but some of the rest is not. It's not pristine for sure. But it is a very special piece. CORRECTION: the tatty but original Moog wooden road case goes with the second Synamp in this auction, not this one. That means that there is no reverb tank at all with this one (the tank sits in one of the wooden case lids) - but a pretty simple job to house and connect a replacement. This example is still seriously heavy and solid without the wooden case.

There will be a second Synamp in this auction in non-working condition, and possibly the massive speaker cabinets (as seen) that they were designed to work with - though their huge power could only really be used in a decent sized space. See lots 30464 and 30465."

"Rhodes - Chroma (s/n 21010234) - In very good physical condition, but does not work as system locks up at boot up. The power supply was replaced previously, so the troublesome Rhodes power supply was replaced prior to the current problem.. Comes with 2 original Chroma footswitches and the Chroma dual pedal unit. 240V (although switch mode power supply – so should be all OK with 110V)"

"It is complete with DKS keyboard and has been recently serviced by the clone circuit designer Derek Revell. It has a gate input modification but apart from that is unmodified.

It's now at VEMIA, and is in great near-mint cosmetic condition. One catch is a little bit fiddly, but that's about the sum of any problems."
