Picked up a Time Pilot, had no sound. I did a few basic things as listed below, and now I have sound (kind of). Certain sound effects fade in & out, certain sounds maintain constant normal volume, and some sounds you can barely hear. This is what i've done so far.
1) Had no ohms on the original 5" 8K speaker, replaced the speaker with new 4" 8K speaker (couldnt find a 5" anywhere).
2) Cleaned & wire brushed every chip on every board.
3) Tested Volume pot on board. Resistance seems normal and ranges from 10K to 0K when it is adjusted.
I did notice that when I turn the volume pot, you can hear the wiper on the inside of the pot come through the speakers as very slight distortion, and i've never heard that before. This would lead me to believe on a bad pot that all volumes for all SFX would be at equal volumes, and not have different SFX fluctuate at separate volumes. Is that correct? What else should I check?
Thanks!
