Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: I sense a lot of head scratching goin on

How much current will your diff amp be drawing? How much bias voltage will there be at the cathode?

It is possible (probable) that you will need a negative supply under the CCS.

Depletion mode MosFets sound much better with more voltage across them.

Without the negative supply the MosFets will have to work with only the bias voltage.

BTW, I edited my post above adding more info.
