Hello,
i was given this amplifier from a friend who was an engineer in a TV station.
This was a DIY amplifier built by their old retired service technician built sometime in the late 70's 80's ?
It was used to power a a pair of Rogers 11 ohm LS3/5a in their dubbing studio.
It has XLR balanced in and that possible the role of the Transformers after the inputs (Large silver spheres) ?
Since i am not very familiar with older Amp designs i need your help in identifying this design ,circuit ,
How good is it ?
Is it worth upgrading modding in order to keep ,can you tell its power rating ?
Any tips , help or mods will be greatly appreciated .
Cheers to all
