Here's the results from my modified SB220
Plate voltage 2500V under load (SSB mode)
Plate current .75A
Grid 230mA
Drive 75 watts
Output 1100 watts (key down, not pep)
Voltage and current readings are from the SB220 internal metering.
Power is measured on a Kenwood SW2000A.
If you are still using a T network, then please change to a PI input
network with the output cap right on the cathode. The Q should be around 4.

Hi Paul,
I 'm working on putting the PI input back in and tweaking it.
