Threshold Stasis 3 biasing for dummies

[rogerh113]

Here is a picture of the board. Got the Stasis 3 as a project with this side blowing fuses. Pretty bad repair job on the main board, with a number of dead transistors and cracked .68 ohm resistors. Does not look like he messed with the piggyback board. I have replaced the electrolytics with like.

I am just starting to troubleshoot the board, and am hooking up the +, -, and ground, and using a variac. Will spend a bit of time tomorrow to get a bit more familiar with the board.

Oh, it is a 5K pot.

all multiturns I know are having setscrew either on top or one narrower side

Found this 4 turn pot, which might well work with a bit of lead adjustment. I think the leads on the original pot are in alignment and these are offset, but should be manageable. Printed out the spec sheet, and will have to measure things out to make sure....

Looks like there are likely other issues on the piggy-back board, so I will have to spend some time on that. When I need more help I will start a new thread.



Thanks again -- Roger
