Already replaced all the resistors that showed any sign of stress.

Yeah, but the TIP31A part is cheap, and is free

What I would do is bolt a tag + wire onto the tab of the old transistor (don't
tell me you don't keep solder tags and small nuts/bolts (M3, 4-40 UNC, whatever)
'in stock' and get it running for the moment. You can then carry on debugging

matches, instead of the 2 x 1.5K parallel pair I had put in.
And also order a replacement transistor and resistors and fit them when they
arrive.
