Hello,
I have to admit it- I have made a partial mess out of my recapping of my old Citation 12 amp.
Probably, the recapping is quite OK but I must have touched something on the board when adjusting the bias, so that when I connected the amp to the speakers, DC of probably quite a lot of amps, Went right into the woofer and destroyed it (Not a very big thing, a few hours work to replace it, but still....)
Now the issue at hand: What shall I do with the amp? I have invested like 200 USD in new caps and one thing could be to replace all transistors. If so, the trouble would be to find adequate replacements (does anyone know that have done this?) Perhaps the transistors are getting oldish after 40+ years??
Another would be to find and replace the one/few that is malfunctioning and that will be a challenge (advice on how to take the first steps in this would be greatly appreciated..)
I NEVER give up! I will have that Cit12 operational att ANY cost in time or dineros!
Best regards//lasse
