RE: red plates ... bob and weave ...

"2.5K seems to be a standard value for a 2a3 at 250V"

2.5k is the standard for a 2a3 at 250volts plate to cathode but at 60ma.

Dennis runs at 43ma.

"Paul Joppa may have eluded to successful use of 2.5K here"

In fact it is Paul's math I used to determine 3.9k.

Paul's math follows the Western Electric chart very well.

If you want the least HD (across the board) while still having some power, it's a good rule of thumb.

load impedance = (voltage / current) - (2.38 * plate resistance)
