Super Regulator

Yes. I’ve recently put it all on stand-offs to be safe.

I am seeing approx. 24V on the outputs with 26.5V input.

Did you look at the output with a scope? I think the superreg needs 5-6V headroom. 2.5V sounds way too less.

I am going to set my voltage around 18V-20V for the Waynes Preamp. I will no longer be trying for +-24V.

I don't have a scope to check but it seems the parts I will try to use should work with the Waynes.

Enough threshold is necessary for any voltage. If you do not have a scope, you should at least use a mV meter to check the output is clean.

I just went through my parts draw and I have almost every part to go with a Wayne’s preamp with 18V+-

I think I’ll go this route to be safe, keep the 6.9V zeneer and use the opa1611.

Any issue with using 26.75V input to drop to 18V-20V with these parts?

I have a 20VAC dual secondary Antek I would like to use.

20 VAC ends up to approx. 30 V DC when rectified. => it works. OPA1611 will probably work fine.
