Jim,

?

In my a-building Grid-Driven 2-holer Tetrode the Breuhne

bridge used for Neutralizing the tubes has a small roller

inductor and both a fixed and variable bread-slicer.

?

Since the Input network is using a 9:1 balun transformer

it will be necessary for me to connect a 450 ohm

Non-Inductive (Dale 50Watter, Green metal case)

resistor between one of the tube socketses G1 pin

and chassis ground.

?

The VNA connects to the RF Input port and the

T/R Input relay will be picked special:

?????????????“Tune for the Least Smoke”

?????????????????????????????? Right?
