Magnasync Moviola URS 5 watt Tube Power Amplifier Squawk Box Combo Lunchbox Amp

  

They did make a few audio products designed to support the large upright and flatbed Moviola film-editing machines which were their main products. The most common of these audio-products is the URS 5-watt tube amplifier with built in 4?

The URS apparently debuted sometime around 1955. Since the tube compliment is 7025 (aka 12AX7) - into 6AQ5 power tube (aka basically lower-voltage rated, small-bottle 6V6) with a single volume pot between the two 7025 stages, this thing is basically.. Yes, there are some important differences - different plate resistor values, no cathode bypass caps on the preamp stages, and i think some frequency compensation in a the feedback loop? But basically a tweed champ. There are online resources on adding a 1/4 jack on the single pin side to turn it into a guitar amp - or you can use it for its original purpose as an amp for gang sequencing & editing 16mm film.

I tested it with the 4-pin connector to a magnetic sound film sequencer I have for 16mm and it sounds great. This amp also has an 8ohm 1/4" mono line (headphone jack) out so you can choose to bypass the on board internal 4" Alnico Speaker and use the URS as an amplifier head for driving an 8ohm load to an external speaker cabinet. There are signs of wear on this URS - some rust and scuffs & scratches + small red marker near red light on unit - see pics, it's in decent shape for it's age.

The metal headphones out label is missing at the 1/4 jack port. Last pic of interior is from another unit (same model URS) for an example. Send me a message if you have any questions.
