Crap Amp Doctor EP04 - HH Electronics - Micro 30

They used to make solid state electronics for the BBC, but do they make decent guitar amps. Speakers is quite good (if it's not faulty), the heart of the amp is a amplifier module as used in a lot of stereos from the 1980s. No schematic was available, the problem was mainly the first stage FET. Do check the thread on freestompboxes.org if you're fighting with a similar beast.
