STOLEN! My twist of the B1 Buffer Preamp by Nelson
If you shall steal you should steal from great designers.
I got very inspired studying the B1 Buffer.
I have redsigned it my way - but basics are still the core.
One difference is the power supply.
I use 2 LM317L. They are TO-92. 3 pins.
I found 2SK170 hard to find and a bit expensive.
I want to buy only here in Sweden.
So I decided on BC264D for JFETs.
I think they can qualify the mS requirement.
Nelson mentions 5-30 mS.
Of course I want a verdict and approval from the master.
Will my circuit do fairly?
Finally I can recommend a visit at the goldmine: Pass DIY.
Therre are so many things to discover: PassDiy

You missed the better sounding Mezmerize/Hypnotize ? Shunt PSU, DC coupled so no expensive caps needed, muting relais etc etc.

The boards are sold out I see. Turn up now and then in Swap Meet.
