Thanks for everyone's input. I contacted Torreson by phone they stated that the YSB and YSE manuals are the same. So I ordered the service and parts manual. I recieved them yesterday (next day service, very impressive). The parts manual says YSB, however the service manual only says YSE there is no refrence to the YSB. I'm curious, those of you with a YSB manual, does it refrence the YSE? Nick
