got a brand new sound board, pcb and power supply from takeman. my filter board is re-flowed and i've went thru the schematic 10x it seems. still no sound. volume pot works in reverse according to the manual. i turn is all the way up counter clockwise and i can hear it hum, clockwise seems to turn it down. verifed all voltages at the ps are correct also. i'm beginning to think that either something is wired wrong at the filter board which i haven't gone thru yet or the volume pot is bad.

Any suggestions?
 
i guess i'll start with the volume pot and go from there. reading thru some old threads it looks common the volume was backwards on these games.
