Was using the radio this morning working fine then something happened now just about 2 watts on Am and about 2 watts on ssb both lower and upper.

Radio dead on frequency and receive is great
No burn marks on the bottom pc side.
I pulled bothe finals 2sc 1969 and 2sc2166 abd both are ok.

Seem like rf out power just dropped in radio.

Any suggestions Im going to get out the service manual later tonight and study it and see if i can figure this out

Forgot to add there is very little modulated audio going out on AM its now backwards modulation and ssb will get a 2 watt carrier this is with a turner hand power mic.

Radio was doing about 15 watts SSB and about 5 watts AM now all low rf out.

thanks for any help
