Dave -

You are correct. The specs for the RK-65 are shown at
     http://www.mgte-dot-com/rk-65-schm.pdf

These specs show the output for the RK-65 as 510 watts. This is less than
the 635 watts for the 833a tube. I was guessing at the 833a tube output but
incorrectly used the 811 output which is about 200 watts. It is obvious I am
not a tube expert. I am sorry if this has caused any inconvenience.

John,
I checked the specs for the RK 65 tubes, vs. the 833a's

Parameter 833A RK-65
Plate current, Class C 400 mA 200 mA
Power output, watts 635 watts 380 watts
Plate voltage 2500 2500

Unless I'm reading the data wrong, it seems that an 833a is worth about two
RK-65s.  Any comments?
Dave
