Hello again...
The problem is solved.
It was C171(390pF), which was defect. Replaced from a "donor" radio.
Now I have 10W AM / FM and 20-25W SSB. Hope someone else will benefit from this too.

I have checked on some components inside the radio now, thought the error was a bipolar electrolyte (C174/2.2uF), instead of an ordinary electrolyte, but it did not help so much. Measure the voltage on the IC9 (SO42), negative 0.4 V on the legs 11 and 13 at the RX, 1.4 V for the TX. Do not know if t...

I mistype in my post, it's TR56, which has power output AM / FM / SSB. It will be the left final (TR56) which has power, as seen from inside the circuit board. Have I only right final TR43 plugged in, then I have no power at all.(It is OK in TR56 position.) So the both finals are OK. The colectors g...

Radio Make and Model: Galaxy II PCB Number: EPT360010A PLL Number: MC145106P Test gear available: Osc, FreqCount, Multimeter... Symptoms: If I only have Final TR43 plugged in, I have abt.8W output on AM. If I plug in Final TR56 also, you can not adjust the output power more than 2-3w AM out. Should ...

check vr14, I had a bad trim pot.
