Also download the QEX article for some basic information about screen
supplies - including ideas to avoid.
But according to the tube data, we're taking about a 1500V screen supply
at 170mA! That's a bit rich for my normal solid-state screen regulator.
However, the Tetrode Boards manual may still provide some design ideas.
For example, you could think about using the solid-state control circuit
with a vacuum-tube shunt regulator. A 4CX250B might just about hack
it... you wouldn't be short of cooling air...
