[QUOTE="Ingvar Ahlberg, post: 841171, member: 15447"] As i see it that is something that should produce a happy face, needs regular, very simple, service to do its best, all switches and potentiometers are open to the environmental efects in that pre. Depending on local RH, up here a mean of 75% i guess, once every 3:rd mont lift cover and spray all switches and pot?s with PRF 7-78 contact cleaning spray, this should be done while the preamp is powered up and the sprayed switch/pot is excersised while spraying. If You use a conducting cleaning spray, do that with preamp switched off!! Ingvar [/QUOTE]
