Aaah - the famous "Magnetic Field Amplifier" design. I'm surprised that there are any of those still about. They were terrible. The exact opposite of KISS....   Dead


Yes indeed. never liked any of the Carver range.  Whenever you see a pile of old non-working spares or repairs amps, garenteed to find a Carver in the there. Oh, and a Hill chameleon too. LOL



You're not wrong there!!  LOL LOL LOL

Door stops:-




What was so wrong with those MT's?!??! Cry

IIRC, the O/P boards were very badly damaged & impossible to repair. I have made use of the other bits, eg. fans, main boards, etc...
