2 versions of the Chop Shop?

[Preverb]

I am about halfway through this build. I remember reading about biasing this and can see older build reports with small internal pots for biasing. The most recent PCB doesn't seem to have the trim pots. So does this mean there is no way to bias the J201s? Or has it been figured out so that this is no longer required with current PCB. Or am I missing something completely?

BTW, Merry Christmas everyone

The trimpots aren't on the board as is.
You can use trimmits and 20K trimpots to replace the 8K2 and 9K1 resistors, or socket those to play with different values.

And you might want to look at this thread.
