I fired up my Tail Gunner II the other day - no BOOM.

It came with the 22K resistor mod, so it was still too loud with that. I'm shifting to the 2.2 k resistor next.

I did ring out the speaker wires and the speaker (new speaker, but with the BOOM, you never know) and they work.

Going into the Audio section, there are two transistors - Q6 and Q7 which look like they could be the culprits.

Symptoms: Audio is kaput. No:
Rumble
Fire Sound
Shield Sound
Nothing.

That's why I went after the audio transistors first.
