Help identifying Radio
Hi All,
I have recently acquired a vintage Radio that I am trying to identify before I restore and thought the collective mind might be able to help This had been rehomed into a new cabinet without a speaker so have little to no markings It has 3 x EL84, 2 x EF86 and 1 x ECC83 plus an EZ81 rectifier. I am a bit confused with the EL84's as there are 3. I can only see a single output transformer. I have attached some pics which hopefully help.. Thanks |

Re: Help identifying Radio
Are you sure it's a radio? I can see no evidence of a tuning capacitor or tuning scale. It looks more like an amplifier.
What's inside the screened box the right hand rotary control goes into?

Re: Help identifying Radio
There's a higher-than-audio frequency coil on the chassis, but I agree that it doesn't look much like a radio, nor does the valve line-up suggest that.
My guess is that it's an amplifier from a tape recorder, the coil being for the bias/erase oscillator. 3 off EL84 could be a push-pull audio output and a separate one for said oscillator. |

Re: Help identifying Radio
Hi
The laced wiring, stencil IDs for the valve types and generally high standard of construction suggest something for the professional market rather than domestic. If for a Tape Deck, I would have said Brenell or Ferrograph but the knob layout doesn't match. |

Re: Help identifying Radio
I was thinking professional kit too - maybe something from a small cinema or factory.

Re: Help identifying Radio
Yep, I guessed radio at first glance but you're right as after a little clean can see some inputs for Tape, Radio and what looks like pick up in the enclosed box?

Re: Help identifying Radio
The box appears to be a pre-amp possibly with correction to suit a pick up.

Re: Help identifying Radio
Probably a 16mm projector unit. The third EL84 probably supplies high frequency for the exciter lamp.

Re: Help identifying Radio
It reminded me of a Truvox tape pre amp I had in about 1959.
