FR speaker on panel is beloved in the Orient. Are you located in Asia by any chance?

Salas,
tested my sk117gr jfets with 9V and 1kR in the drain and they came in much higer thatn expected. In the 7mA range. I am wondering if it is a function of low Vds. Are these usable by dropping the 6.8K resistor or exchanging for lower value? Calculator suggest that 2.2K can be substituted and I should be OK. I figured 70mA load current since I will be running both channels of one shunt. Just want to make sure before firing up.

They should be 6.5mA max by Toshiba data. Use 10R for drain resistor Vdrop IDSS evaluation. If they are genuine and really in the higher GR range tier then you can fix that see text area series resistor to the trimmer accordingly.

Didn't really mess with this at all since breaking leg of one 9530 in the SSLV1.1. Ordered some more but did not get here. Went ahead and finished the Salas reg. Current setting resistos is parallel 120 and 15, for 13.3R. Shunt current of around 250mA. Probablly low for 2 channels, but don't really want to push sinks any more. Got 36V across output, loaded with 960R. Will trim to boards when attached. Tomorrow. I am tired and have to work tommorrow morning in the cold. Bla! The "plan" is to listen tomorrow or Sunday.

FYI,
This is the folded version I am building.

Its not low, just not too hot-rod. Two channels like you linked will suck only 70mA out of a single supply.
