[TenTec] Re: PW-1

[Jim Cox]

I think my previous message went but not sure... I think on your board
layout like mine here, D18 is the first diode not the second as you
state....  I think the first one is D19 which shows up on the service manual
schematic and board layout but is not there on the newer models of the amp.
