Small bear sell these new, they're back in production.

Would these circuits work much differently on a dual rail supply? +/-15v

You may try J201, or 2SK30.

I mean for the clipping transistor. Those things were expensive now I have a pile of them to use up.

Would a ztx951 do? I still have a few of those things left.

You seem to be missing two of the cuts on the underside?

If you know how to etch your own PCBs its possible to make smd to to92 adapter boards, its what I do for my pedals. You can buy them premade but the ones I've seen are way too expensive to be worth it.

My version of this
220pf Compensation Cap, B1k honey pot, trimpot on drain with 2n7000 mosfet, 10k resistor and 4.7nf cap to ground on output to volume pot.
