While biasing my 1974 MM 212 HD130 after new tubes, I mistakenly tweaked on the tremolo trim pot and now the tremolo circuit isn't functioning correctly. The problem seems to be more with the intensity rather then speed although both adjustments aren't working correctly when tremolo is switched on. All the caps and resistors appear intact, so I'm thinking I may have damaged the TR1 or TR2?
I'd like to try replacing TR1 & TR2 to eliminate those components, but don't know how to identify them? I'm surprised at how little component information is available. I'm looking for a component layout diagram for a HD130 amp and associated component parts list - specifically TR1 and 2. Any help would be greatly appreciated.
