[Amps] Dual Band 2m / 70cm PA

[David Smith]

Does anyone know of a design for a valve PA that covers both 2m & 70cm using 
the same tube?

I'm thinking about a compact PA for these two bands, possibly using a HV PSU 
from a Panasonic "Inverter" microwave, if I can get it to work.

Is it possible to design a common plate line, given that the bands are 
harmonically related (e.g. 1/4 WL on 2m = 3/4 WL on 70cm)?
