I recently aquired a LK-500B with QSK that needs some work.  I have the original manual and schematic but these leave a lot to be desired.  I have a QSK/VOX switch on the back of the amp, but not on the schematic, two connections marked "2 purple wires" on the schematic that God only knows what they connect to, etc.  I have downloaded the BAMA copy and it is basicly the same manual that I have except many of the pages still reference the "LK-500A" version on my original with a few items changed to "LK-500B".    Anyone have a better copy of the "B" version schematic or maybe a copy of the "C" version might be helpful and more complete.  Since the owner of Omega is now SK, who is now the best source of info and parts?  Anyone taking over Omega?  I have read here that there is some kind of tube protection on the "B" version and more on the "C".  I see nothing on the schematic and nothing mentioned in the manual.  Can anyone clarify this please???

Thank you,
