Hi John

Interesting looking AMP, it looks like a direct copy of the OMPOWER
designs. Thats hardly surprising, its Chinese made!

The last thing we need is a another substandard IMD performing tetrode amplifier on the ham bands.

Its bad enough that these tubes are getting hard to get. Being left high and dry like the many TenTec owners with the 4c1600 tube thats impossible too obtain is enough reason to avoid the chinese made FU728 tube.

The crummy signals from these tetrode amplifiers is  also another  not  too buy any of these russian/chinese tetrode amplifiers.

If it was my money I would buy something with a Eimac 8877 or 3cx800 in it. At least you get acceptable IMD performance even from the Chinese copies of these tubes.
