Mike, very few builders in the US use temp tracking electronic regulated bias, off hand I can think of one person that does this on 11 meter amps that does it well, and it's not cheap.

That bias is just resistor providing bias voltage or temperature compensated bias circuit as it should be done?
Mike

His bias circuit is crap. Schottky clamping diode/resistors
