Anyone know a good amp technician somewhere midlands area uk?
Just looking for a service on a jcm800, I know marshall bias the valves a bit cold to prolong their life on new amps, I want to heat it up a bit.
If I wanted to do it myself, are there any special tools apart from a mulitmeter that i'd need, like an oscilliscope?
