I am rebuilding a pair of JansZen Z-600A speakers. It is obvious that someone has been into the cross-over/power supply. It seems to me that the two speakers should have identical parts and circuitry. I have downloaded the print schematic that is available, but it doesn't show all of the part values; for example the regulator diode has no description and several resistors shown in the circuit aren't identified.
Does anyone have additional info? I need to rebuild these, but since someone stuck additional parts on one board, and even changed wiring to the tweeters. I'd like to restore it to original design, but without values of the components, it's going to be pretty difficult.
