Are you testing in AM or SSB transmit? I would stay in AM, and know SSB does not have a steady carrier like AM, with no modulation.
R60 pulled is only switching off DC control voltage for D20 the RX SSB switch.
D20 along with D3 switch the Rx between AM and SSB I think. It is confusing because that same circuit block is dual-purpose, used for Rx and Tx.
So the RX switch could be stuck on, you could try lift one leg of D20 to unload that, if it's the problem.
It's normal to lose a lot of signal in a crystal filter like FT3, which IC5 makes up for. So don't expect a lot of signal at IC5 pins 7-8 and go on a goosechase.
Confirm the voltages are good at:
Node #2 8.2V rail, feeds Nodes #2-8.
Node #4 7.42V SSB/6.13V AM XMT
Node #11 7.09V AM source
Node #12 8.2V XMT(A and B) source, will also switch on TX lamp "On the air".
Who is R30?
