Tannoy SR840 Amp…questions

[Barry]

I'm not sure if they have anything to do with valves. The SR840 is an amp designed to power the Tannoy monitor speakers. Surprisingly for a professional amplifier the XLR inputs are not balanced, so I believe the octal sockets were to allow transformers to be fitted to make the amp fully balanced.

Jesper's friend will easily find out what they are for, though it is surprising that the transformers are missing.

My thoughts/concern exactly Macca

Not that I’m an expert quite the opposite, and the main reason why I’m in here asking you guys & girls
I was hoping that someone in here might have some knowledge/experience with this “mod”

The amp came from a sound studio here in Denmark, unfortunately the guy who had it is now passed away
I brought it from his son

Traffos would make more sense.

Must have been robbed out for some other purpose. I know it does happen that they mod and cannibalise equipment in studios or at least they did years ago,

Thanks guys

I’m sure you’re on the right track…as mentioned, I completely in over my head here, hence my post

Hopefully the repair shop know what it is and what’s missing…

Hi again

I’m “bumping” this post again
- as I’m still hoping that one of you lovely people have had this amp & might know what this actually is

Thanks up front for your time
Kind regards

Oh, forgot to mention that I’ll try to keep costs down by buying as many off the “parts” before I send it off to the repair shop
I’m already sourcing out a bunch of new stuff
