I would suggest battery bias of the CCS plate loads. 2x 3.3V Li-Ion button cells, perhaps 3 of them. You'll need to add cathode-cathode connected 18V 500 mW zener diode pairs to protect the gate-source voltage limit of +/- 20V. A good .033-.1 uF capacitor to R-C decouple the batteries from the gate is also recomended.at 2x bateries, R-3 is ~910 R. With 3x it goes to ~1k2 Ohms.
Enjoy for a bit...don't tweak too quickly. How are you guys fixed for gain?
