When the radio is keyed/TX in AM mode; the meter/radio output swings to full 15w w/o any modulation. Radio is otherwise fine on SSB when in TX or RX. I changed the 2SB754 transistor already thinking that was the problem; but no luck with that.
See if the gurus know about this one.
The schematic here is for a Galaxy 77 radio; but it is basically the same radio (3900 chassis):
