what exactly are you looking to do? is it a tuning coil you are looking to adjust, or do you have a 'no audio/modulation' issue you're trying to fix?

it has very low modulation, keys 2 watts swings 4 watts. i have tried all the tune ups with no luck. cut the resistor just to see, no help so i soldered it back. i have replaced the final with no luck. i was just thinking that the modulation transformer was weak. i have a parts radio to steal it from i just need to know where it is. im think its the large transformer toward the rear of the radio on the power cord side. but wanted to make sure first.
thanks
