I have a galaxy dx-77hml that is overmodulated and flat topping on the scope. I fixed tr-53 and the tr32 and removed the swing kit. i looked until i was crosseyed and i cant find anything else that was hacked up. i checked a couple transistors in the amc circuit and they all check ok. the modulation control pot still has no control over the modulation limit. i did find hovever that there is supposed to be .7 volts on the base of tr32 and it is not present. I am still looking for the problem but i was looking to see if any of you well seasoned guys (rick) might be able to shed some light on my problem.

thanks,

Mike

well i am going to answer my own question here. Just found the problem i found that D70 was cut and it was hiding under the wiring by the echo board. well maybe this will help someone else who is trying to fix up someone elses snip and clip job.
