This is one of the more interesting jobs I’ve had. The Q-Chord Omnichord which is actually made by the Suzuki Corporation. The current owner of this one took a gamble on buying it in a broken state. It looked as if a previous owner had not noticed all the screws that hold the covers together and had tried to prise it apart with a screwdriver. The PCB inside had a big crack in it and the DC power input jack was mashed. I did manage to get it all working in the end though you had to press quite hard on some of the chord buttons on one row to get them to sound. They use a conductive rubber pad under the button sheet to make contact. I cleaned the pads as best I could and guessed that with use they might improve. This model has a rhythm section. The plinky plonky tune (in a key to match the chord button currently playing) that is created by touching the touch sensitive strip to the right is quite delightful.
Here is a photo of another one I have just been working on: The Omnichord OM-84.
I (Dan) do the sound at the Red Cross fundraiser music festival at the Old Hall Hotel in Hope, Derbyshire at Easter weekend every year.
I use a thermionic valve (or vacuum tube) tester based on the excellent uTracer 3 circuit board designed and supplied as a kit by the Dutch wife and husband partnership Marie-José den Brok and Ronald Dekker. See https://www.dos4ever.com/uTracer3/uTracer3_pag0.html
Here Jennie Nell with her Kawai MP6 stage piano. It had a blown -15 Volt regulator on the internal power supply board. Nice keyboard to work on, easy to disassemble. It all powered up and showed a display because the main logic board was powered but there was no audio signal from the output jacks or headphones. It is all fixed now.
This is the prettiest flight case I have ever had in my shop!

Trace Elliot manufacturing, what were you thinking?! Expensive looking collet knobs on splined potentiometer shafts. They didn’t even put little shims in the slots as I have seen some manufacturers do so the slot closes up. The knobs just go on wonky and come loose so you would be paying for this lazy solution when the warranty claims start rolling in.
By the way folks. Don’t ever try to prise the slot apart, the metal breaks so easily and you end up paying for a new potentiometer. The only technique I found to get them to stay on was to give them a really good tighten with a good driver and hope for the best.

The laney TT100 service manual does not give a simple layout diagram to show which valve is which and what it does so I have posted one here. Click image for bigger picture. For the schematics see here: laney_tt100_sch
