Where do the ground wires go?

Alright, well if you promise there's no solder bridges let's move on to voltages. Measure the voltage on all three legs of both transistors, and that should give us a good idea what's happening. Also measure your battery voltage so we have a reference of what voltage to expect where.

Aside from voltages I would also like to recommend an audio probe. Mine has helped me trace the problem on dozens of builds.

The region around 2 orange & purple wires is VERY suspicious..!!

Should I measure each individual leg or the entire transistor?

Not sure how to go about the individual leg way.

Black lead on GND and Red lead on any individual leg..
(or vice versa, ignoring the minus sign, but maintain the same leads orientation for all measurements..)

Hahaha yeah, it looked it to me. Nothing is touching. I'll do some cleaning up and see if that works

Power is being drawn up until the first transistor at which reads 0.

Fried transistor?

All three legs?

[Cmwm]

Yes, everything after that is reading at 0.

Battery is checking at 9.7, that's present up until I check the first transistor.

Mmkay, well that's a pretty good indication of a problem. Are you getting 9V on the top leg of the 51k and 20k resistors that go between the battery and the collectors of the two resistors? That would be the first place I would check. If your transistors aren't getting any juice they aren't going to work very well
