Traynors run pretty hot, here is my Traynor with 6ca7's. 580v plates, 556v screens. Measured 85 clean watts out of a pair of tubes.

Around 1970 I was a repair tech at a music store that sold Traynor. I recall that their circuit designs and tube complements were roughly similar to Marshall, Hiwatt, and Orange amps of that same late 1960’s vintage. The primary difference was that the Traynor amps came from Canada rather than from the UK.

I will dig around in my files. I might have a couple of Traynor schematics. If I find any I will scan and post them here.

Traynor schematics are not hard to find on the web and OP has one already. Voltages are not critical but you need to watch total tube dissipation. Any 7027 you can buy today will not be like a older tube which are more robust. Chances are that same model used more than a few different output tubes. Traynor often taped the factory schematic to the top hinged cover. A lot of models were 95% Marshall copies.

The story is that Mr. Traynor would test his new designs by dropping them from the roof of his shop. I imagine tubes were pulled first. 8)

Note: This amp is sitting there upside down. Makeshift work bench, that was a year we moved.
