Upgraded the heat sinks on the PWR supply board, replaced 6 electrolytic caps, all the transistors and switching diodes attached to heatsinks and both BASH chips for less than $100.00. The system sound ridiculously good. I purchased Klipsh 2.1 in the interim and they sound good but just don't...
Complaint:NO Sound from SAT or Sub-Only highpitch whine sound from SATS.
Replaced all MOSFETS and DIODES on pwr supply board and digital converter board.
Replaced 3-22uF Caps and 3-47uF Caps.
Replaced BASH chip on Sub side.
Tested. Sub now works.
Sat still have high pitch whine...
