Fet trouble

Thank you Martin Manning
for your battery bias method
Works like a charm. I solder post
on the Fet board use two 10k pots
makes changing resistors fast.

Glad to help out. I need to do some more looking into tweaking the bias point with the source vs. drain resistor. My gut feel is that keeping the drain at 10k will preserve headroom, but I'd like to understand it fully.
