Recently received this automatic amplifier from OM Power and am very pleased and impressed. The menu system is simple and informative and the amplifier works perfectly with many protection circuits. Very compact and light weight given that it is a tube amplifier.

Have had the new version of the 2000+, with new touch screen, for a while now. This is a very compact, stout, full legal limit amplifier, running the FU728F. When I say legal limit, it means it is just loafing along at legal limit, with around 25W drive. Very intuitive touch screen

Tuning is very straightforward and easy. It came with a test sheet of the maximum outputs for each band and the tune and load settings. A great help to see where to ballpark the tune and load. Once you choose the band with the enormous knob... apply a small amount of drive and

This amp peaks easily way over 5 KWout in SSB but provides also the best IMD-spectrum I have measured so far @ 1,5 KWout: -42dBc on 20m. Gain is very good (typical for modern tetrodes). 22W is enough for 3 KWout. No matter what you need - this amp is a real beast.

I owned my 2501a for nearly 3 years it is a great piece of engineering and has so many safety features to protect the user who makes a mistake. And they come on instantly. The gu84 is a very robust tube. I'm not a technical person and at first I found it daunting when you

The amplifier is very easy to use. After a 3-minute warm-up phase, it really gets going. Continuous operation for many hours at over 1500 watts is no problem. The fans are very quiet. The new display offers numerous settings (antennas, color, and other parameters). I'm very satisfied and

After several months of struggles, I found the problem. Tuning, that is adjusting the tuning per the presets provided with the amp, is critical. Then this box will deliver output per specs. And it is built like a WW II battleship - boat anchor but what a boat anchor and pleasure to own and operate.
