Help identifying transformers

Post by Joe Bilge »

Hi
I got this set of transformers about 25 years ago to build a tube amp. Since then, I've built many tube amps, but never got round to using this set.
Can anyone identify what make they are? I always suspected they were Partridge, but they don't have the regular Partridge badge on them, but it could have been on the board that was clearly broken when they were stripped out. After that I thought maybe Parmeko.
I was told they were for a pair of KT66s, they seem quite oversize for that; definitely larger than the transformers in a 100w Hiwatt or Marshall. The power one weighs about 6kg, the output one about 4kg.
I have calculated the ratios in the output and it comes out with a primary of about 4.8k.
At the moment I'm just trying to figure out the make.
Anyway, thanks in advance for any info, hopefully the photo has uploaded ok (posting from phone).

They do look Partridge like , but I would not put money down on it.

Maybe someone else will add info.
