General Radio Genrad W5MT3A Metered Variac Transformer This is a model W5MT3A Metered Variac. The W5MT3A is a classic, and built to last. Open the gray hammertone cast aluminum case and you'll see quality construction that's hard to find nowadays. Like all Variacs, the W5MT3A provides a simple, rugged method of controlling electrical AC voltage for repair technicians and design engineers. It takes in 120 volts AC and provides continuously adjustable output voltage, from zero volts to 140 volts AC. It provides excellent load regulation with negligible variation in output voltage from no-load to full-load current. The W5MT3A features a built-in voltmeter and ammeter with two current ranges, 1A and 5A. Has three-prong receptacle output.  5 amp output rating.  Note: variacs do not provide isolation. Always use a separate isolation transformer when isolation is required. If you're buying vintage tube amps, tubed radios or test equipment, you need a way to bring them up to working voltage slowly after being in storage, to prevent damage. In that case, you need a variac as much as you need a good digital volt meter.  If you've got a vintage amp that you want to run at the 110 volts it was originally designed for, the classic styling and metered output of the W5MT3A will make a perfect match. Condition The ammeter needle is a little sticky, and there are some scratches to the top of the cabinet.  Otherwise this unit is in excellent working condition and is very clean.
