Vintage Audio component -- Identification help please

[glasswave]

I got an SAE audio rack given to me by a friend. In the rack were several components.

• a Nikko ND-790 cassette deck
• a Nikko Gamma 40 Tuner
• an Audionics of Oregon BT-2 preamp (this is what caught my attention)
  
• an SAE model 2800 parametric equalizer

and a mystery component which I cannot ID:
It has 6 ten guage cables coming out (3 per side) with banana plug ends

can anyone tell me what it is? I am guessing some sort of amp.

It appears to be a level control for the speakers but not sure why the transformers.

It is not an amp but is a volume control system for remote speakers - likely in other rooms. In other words, it is a distribution system with a volume control for each channel.

I'll bet if you take a pic of the specs/label on those transformers, they'll be spec'd as 70 volt.

Cheers,

David
