Are those axial lead silver caps on that board Polystyrene
Might also be a crucial element to the tone of this circuit along with just values , if so?
The one I built "works" but the sweep goes to an awful extreme bass end. I used a .0082 rather than .0068 uf cap and didn't think it would matter much , but I'm wondering if those cap values (.0022, .0068, and .015) might be the most important to be ALL dead on for this thing to have a usable pleasant sweep??First I thought it was the Twin resistors that needed to be Exact but I have them at 183k each now and there's no difference at all from 120-150k in those positions.
I also wish that someone would have that layout worked out as it is in yours ! I can ALMOST see it well enough to get the layout right but I would probably need a closer shot. I really like the long narrow PCB and the way the board is populated.
