[ARC5] Reconfigured BC-456-E modulator to audio amp?

[Nico van Dongen]

I bought some ARC-5 and SCR-274-N parts and with it came a totally
rebuild BC-456-E modulator. Perhaps it was converted to an intercom and/or
audio amplifier.
It contains two VR150 voltage stabilizers and one 12J5 triode and three
relays. The conversion was done to a higher standard than the average
amateur will work.
All original plugs on the chassis are rewired so I assume it was intended
to be used in combination with the ARC-5 or SCR-274-N installation.

Does it ring a bell the someone?
