Do you have any 7915s? You could use wires to connect a TO-220 if the leads won't fit.

I installed a 7915ct and I now have -15.2 volts on the output. I’m still down one channel but making progress

 

[Perry Babin]

LEDs on or off on the dead channel?

 

[RockfordFIx]

Off

 

[Perry Babin]

Same channel dead?

DCV across R218 and R217?

 

[RockfordFIx]

14.5 vdc on 218, 217, 117, and 118

 

[Perry Babin]

Do the LEDs flash on for a second like they were doing?

Apparently i blew open the flame resistor R130 when I shorted the Eyelet with my volt probe. Now that I have replaced it both channels power up as they should. I ordered replacement negative and positive regulators to finish the repair.
