Maxon noise gate question

[Kipper4]

I would like to make the maxon noise gate. You can find it on the other forum.
My dumb ass has asked this before here. But I can't for the life of me find it which makes me sad having to ask again.
What replacement transistors please?
2sc1815bl
2sk30a

I'm sure Larry said somewhere

Please refresh my memory. It's my age don't you know.
Thanks
Rich

Maybe the fet 2sk30a could be replaced with a 2n5457
Edit;
Btw I'm thinking of subbing the tl022 with a tl072
Anyone foresee any problems with this?

The 2N5457 is a pretty good replacement for the 2SK30.

The 2SC1815bBL can be replaced with a 2N5088 for similar HFE.

Mind the pin out on both replacements for they are not the same.

Will do Larry thanks you saved the day again.
