SW3 and C3 and TR1 are the keying relays drive do not put a cap on the coil it will cause an over current and pop the transistor.
It would take 4.7 uf to work. But you are right if he could read a schematic the question would not have been asked.That's plausible if you put a few thousand mfd on there. I do like the other method but if a guy could reference the schematic and figure it out he probably wouldn't have asked.
The best advise is the best advice.It would take 4.7 uf to work. But you are right if he could read a schematic the question would not have been asked.
Best advice I can give is to sell that amp and buy one rigged for ssb.
