What transformers does the ADR F769x-r use?

[Sammas]

I know some came equipped with Sowter's, but does anyone know what model they are?

I can pop mine open in a couple days, but I'm pretty sure I remember them being Carnhill transfomers.

ADR units often used octal plugin Gardner transformers.

there were pictures around from our member bernbrue IIRC. Drop him a pm

My unit had Haufe transformers on board.
Unfortunately I sold it, but I think I have some pictures around.

Ah, you're talking about a 769, mine was a 760XRS or something

the very old adr units were equipped with guardner transformers

the f769x, e900, f760 etc had sowters if they were ordered with the transformer option from the factory

the former german distributor elmus from berlin fitted haufe transformers into the adr units.

I still have some original sowter transformers from a f760x-rs laying around so I can tell you the exact component part.
