Your amp looks like it lines up with version "7B."

A truly useful site, btw, Roe!

Indeed, but it's even better with photos and working links

Fantastic chronology by our own Marshall guru!
I learn a ton every time I read something that Roe has written. Lots of great historical info. Always very impressive!

Yes! Thanks, I have indeed been looking at the www.amparchives.com version. It's been super helpful. I agree, I think I basically have 7B as well, although not everything in their description matches exactly with mine, but it's close.

Any recommendations on the best transformers? If there's a good new option that does justice to the original, I don't feel the need to have actual originals on this amp.

One good source is Brian Wallace at Marstran Transformers. His trannies are built by Heyboer to his specs. Have patience for a reply, but he’ll set you up with the proper iron…: https://marstran.com/
