Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.
 ;

Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
