[TechAssist] Re: Zenith SE2517P Chassis 9-707 No audio. Need schematic.

     Russ are you monitoring this if so can you till me where C3418 is. We did 
what the tip said and the audio came back. We found CX3418 an 470uf @ 50V. 
Changed that, no help. Why can?t we just leave those diodes disconnected? Audio 
sounds OK. Thanks

bad 18v supply rail at pin 2 of IC 101 & 201 on 9-599, scope it for ripple
lift biasing diodes at pin 2 of each IC, if audio comes back may have leaky 
C3418 filter cap. on 9-520
