In this video I clean and lubricate the various potentiometers and switches of a mixer channel I removed from a vintage Tascam 244 Portastudio in a previous video. You can follow a smilar process for most audio mixers and other analogue cassette and tape multitrack recorders e.g Tascam, Yamaha, Fostex, etc.
Its a three step process -
1) use contact cleaner and physical agitation- thats moving the switches and pots a bit - to loosen and dirt inside the recesses
2) blow the dirty contact fluid out of the recesses and soak up the excess. I use an adapted airbed pump but cans of compressed air do fine.
3) Apply an appropriate electrical lubricant - in my case Caig Deoxit Fader Lube, but there are alternatives - to all moving parts.
I'll be following this video with one showing how I pry open the cavity of the fader to get a serious build-up of dust and debris clear of the contacts...its not always necessary, but this unit was pretty neglected when I got hold of it.
