Yep,  after I have the CCI 300w kit running I will build a 8877 for 
HF/6m.  I have the advantage ofhaving a spare 8877 and already 
running a 8877on 2m so the control panel and HV PS will be 
shared.  So all I have to build is the RF compartment.  Love those 
triode gg amps.

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.
