Crack knocked off table. Sound from right channel very quiet. 0v on terminal 1 [resolved]

[charlie.waid]

Had the crack knocked off a table during a party. 2 pins broke off 9pin and were lodged in the sockets, pulled them out and socket seems undamaged. Right channel audio coming through whisper quiet. Voltages as follows:

1) .3
2) 190
3) 0
4) 190
5) 84.3
6) 0
7) 75.4
8) 0
9) 114.8
10) 0

Only LED that does not light (including speedball LEDs) is bridge between center of 9 pin and A8. I have reflowed those joints as well as joints on terminal 1 and B1

Both tubes were swapped out to ensure they would not be the issue

Is it possible something was damaged in the fall? Or is there somewhere else I should be looking?

What are the OA and OB voltages on the smaller Speedball PC board?

 

[charlie.waid]

OA is 0v
OB is 86v

Now that I've looked closer at the speedball, Q1A is damaged. One of the leads is loose from the PN2907A. I imagine this may be the culprit?

 

[Paul Birkeland]

Yes, that will definitely do it.

Ok I've got a replacement ordered with DigiKey. Will install next week on arrival and report back. Thanks for guidance

Got new part installed. Nothing lit up at first until I noticed the black wire from 3U to B-A/B had come a little loose on the 3U connection. After reflowing that, crack is working again. Thank you for your guidance
