Review: Works fine - Worked well for me repairing older ham radio amps.
Review: works. - Works great. heavy and sturdy construction. I did notice as many others did that the voltage dialed in on the adjustment knob does not match the voltage on the voltmeter. I used a separate voltmeter and verified that the analog meter in this device is accurate. It should be noted that the unit is designed for 110 Volts so if your supply volts is 120 to 125 volts then there will be a disparity between the indicated voltage and the dialed in volts. Nothing to worry about. I am using this device to power an old vaccum tube amplifier that needs 110 volts to prevent frying the tubes with 125 Volts. so happy i got this. :)

## Questions & Answers

**Q: this can power 2 things at once I assume?  can they both be high power requirements?**
A: Hello, this regulator can power 2 appliances at the same time, but please make sure that the total rated power of both appliances is less than 1500W.

**Q: I have an airport taxiway light with bulb rated 6.6 a, 120vac, 45 w.  plugged in to standard 120v receptacle and bulb blew immediately.  will this wor**
A: Something is wrong with the arithmetic.  6.6 amps at 120V is 792 W.  So, if the bulb is really 45 watts then the voltage should be 6.8, (Power equal voltage times current).  Obviously the bulb is NOT 120V since it blew when you plugged it in.  Taxiway lights are dim so the 45 watts may be right.  Or it may be 450 Watts but that would be very bright and still much less than 6.6 amps.

**Q: Can this dim (control) heat lamps? (4 @ 250W)**
A: Yes, it can dim a resistive load and should handle 4 easily as they are 2.5amp each and the variac is rated for 20amp

**Q: Am i able to buy replacement brushes from you or should they be sourced from another seller?**
A: Hello, we do not provide brushes separately, if you find replacement brushes in other merchants, you can try

### ⭐⭐⭐⭐ It works great but for accuracy I have to monitor the output voltage with a volt meter.
*by G***M on May 23, 2020*

The dial indicator reads low by 20 volts at full scale (so it cranks out 150 VAC not just 130 VAC as specified. The built-in analog meter is small and inaccurate as well. It reads low too. But if I need accuracy I use my own meter. It does not isolate but doesn't claim too either. I use a separate isolation transformer for that. I like the overall quality and feel for the money. I'd order the same brand again if I needed another one.
