I rebuilt my power supply and got my qbert working again but the sound board appears to be dead. I just get a hissing sound out of the speaker when I have the sound board installed.
- Voltages are good now that I have rebuilt the power supply.
- The sound board has no discoloration. Nothing burnt. It looks really clean
- The heat sink on the LM379S did not give off any heat after playing for 10 minutes. Considering the size of the heatsink I assumed it would be warm.
