Default First Watt F5 as I/V stage?


I like the sound from my F5 very much, and also the simple configuration.

So I was wandering to make an alternative to my D1 output stage using JFETs instead of MOS-FET. But could not find any here...

Next thought was to use the F5 schematic as I/V converter, with input (gates) grounded and input at the source...something like this:


but with the 180R removed and input grounded and 10R instead of 220R...and the 5K6 feedback as I/V resistor, perhaps reduced to 470R?

Will it work? What will input resistance be? How to best adjust to zero volt on input and output?

DACs are PCM63P...
