Have you had a tech's opinion on it yet?
They're simple and robust amps and quite rebuildable.
Where in NZ are you?
Matt(?) at Orchard amplification in Wellington is good with Jansens and knows a man in Foxton who can rewind Jansen transformers. Ryan from The Amp Shop in Auckland sure knows a thing or two about Bassmans too. He can supply JJ 7027A's at very reasonable cost and he has successfully converted a few 1970's Bass 75 amps to run 6550's in the output stage.
I'm in New Plymouth and our tech here is Tony Baxter.
I've got a late 1960's 75 Bassman which I really like.
