Wood River, IL
I've got an A-16917 DCS board that had some previous work done on it (of arguable quality).
It had really poor quality sound, noise and low volume output. Started working on it and around some of the issues created by the previous board work.
Replaced C20, C21, The TDA2030A's at U27 and 28, the TL084's at U21 and U29. I also replaced all of the resistors and capacitors in the low pass and high pass filter sections. Toned all the connections out, confirmed the resistors.
The sound quality is great. The cabinet speaker is nice and loud but the volume output out of the backbox speakers, though clear is at a much lower volume than the cabinet woofer.
