Hello Norm,

I would agree, especally if it can be driven to full output with 10 watts
and I had the tubes already. The 4CX250B tubes have been sitting in
my desk draw for a number of years now waiting for me to tire of
my 200 watt brick.

Please provide additional information on your project as it develops. I
plan to post my effort to my website. There are lots of SB-200 amps
around cheap that would make great baselines for conversion to 6 meter
low drive units with a tube change.
