Should I use a shielded wire here?

Post by Encom »

Hello, I have an adjustable voltage divider right before my third gain stage. I have been wondering if I should keep this wire as short as possible and maybe use a shielded wire in this spot. What do you guys think?
Thanks

personally i wouldn't shield that wire but i would shield the wire to that next stage's grid
yeah of course make all wires as short as feasible. no need having cbs fender spaghetti in there potentially oscillating

Where would you ground the shield for that wire?

Since that pot’s case is at ground then just land the shield there.

I also think I would try and use a pot with a nylon shaft, or atleast no full metal knob.

If this is to be a internal multi turn trim pot then disregard what I just posted.

Ok thanks, why a nylon shaft instead of metal? Oh, ground loops when you touch it?
