Hi Peter,
Checking the specs it needs about the same +2.5V on the gate as the original but that is at 7.2V VDs. I haven't set the bias yet, with the FET out the range was 2 to 3 volts over R131's full range. It's now on the test bench so will post the results over the weekend! BTW the old MosFET showed a fair amount of temperature drift
Cheers
