In going through my old computer, I found a series of videos of Kevin working on an Arp 2600. Most likely late 2012, from the file names.
This is from a Moog55, late 2010/early 2011.
More will be featured from this particular unit, as it’s got quite a story!
Video dated 10/9/11
Found this in Kevin’s “work” folder:
Open High-Hat decay extension
DO NOT USE EXTREMELY HOT WATER!
If you ignore that, this is what will happen:
*Paint on knob markers will be removed. (Do not use solvents to clean knobs!!)
*Slide switch has a piece of paper that acts as a very necessary dust cover that can be warped. (Can also be warped by solvents.)
Replacing is difficult to do (see below), so do all you can to avoid damaging the paper.
Get 1 side of switch wet w/a q-tip and flick switch over.
Disassemble switch with mini channel lock pliers and flatten the dust cover via iron or vice
*The resistive elements of pots (esp 1 meg) can be damaged
…and it’s verified as being worked on by Kevin due to his feet being in the picture. 😉
All the black resistors on the VCO board are either 1% or .1% tolerance. FYI, there are 6 sets of 3 matched resistors that are vital to the synth staying in tune and tracking well. Kevin started replacing these during the last few years he was working on Minis.
Happy VCO Day!
Kevin has been gone a year. I miss him, but I’m doing my best to live a life worthy of his sacrifice.
