Is there a source for the two-layer PCB that is attached to some Gottlieb decagon units? I can't find them on the PBR catalog. Searched ebay and only found full decagon units for scavenging. The ones on the Soccer I'm restoring have been hacked to pieces with flattened copper bus wire pieces soldered to them to replace work out traces. Could have been done cleaner but getting new ones to install would be better.
