Which OT for 1972 Superlead?

[guitarjesus]

Hey guys, I'm the new kid around here. I've got a 1972 Marshall Superlead that's been in my garage for the better part of a decade with a smoked output transformer.

I need to buy a new one obviously but I can't seem to confirm which appropriate model would be period correct. I loved the amp before it blew so I want to retain the original sound as much as possible.

I know they had switched to Dagnall by 72, but were they the c1998, c2668 or a different transformer?

Any help is appreciated.

i'd get that rewound. original iron is a big deal if you ever decide to sell it
