Have the TX coils been peaked yet?
Did you play with cap values?

Everything's been peaked out.....i have been playing with the caps and haven't done any good so far......guess i haven't hit the right one yet. The radio has not been used in about 20 year my friend had told me. It was his dads first radio so i am very cautious with it.
 
Was it broke when you got it? If not put it back to stock and then give it a nice easy peak/tune and be done. The mosfet mod for older 29's is not a simple direct swap. I think cb tricks has the step by step instructions. Good luck.
