Somebody did a nice job on those schematics!I used to work on a lot of Yorkville stuff so I have a few contacts with the corp.If you want to post some pics of the guts we can speculate about the parts that look original but don't match the schem.
Our band used to play in Ontario a lot, they seemed to like us there. A gig in Chatham I liked.Canada had a huge import duty on guitar amps and PAs. like 50%. SO Canadian bands used Traynor a lot, as it was home grown. I saw a lot of Traynor over there. I liked Traynor. Roomy inside, and built like a tank.Traynor the company was always supportive. Always ready with schematics or parts. And I always felt you got a good deal of equipment for your dollar with them. Can't go wrong with Traynor. If you will, they were like the Peavey of Canada.
