Some Sams photofacts have a picture of PCB boards with parts as a reference!!! Double check to see if your chassis has this. Also , have you ever etched a PCB??? Ratshack still has limited supplies to do this, larger electronic suppliers would have more PCB options(such as double sided copper boards, etc). If you have experience doing this consider this an option, using Sams pictures of PCB as a template, these are actual size I believe. Maybe your best bet as I doubt anyone would have replacement in stock. A set I have shows half darkened PCB and runs great, some circuits just run hot & tubes, crisping PCBs over the years. It's a matter of time before my set will need this remedy. Junker set available????
