good preamp

This is my play to perjury today good circuit. Listening to the symphony very good. Sound is worse than electron tubes. to offer it fou you reference.

about it

Each 4 JFET. Fully electronic tube circuit, economic and durable, can match with the high-grade stage, sound quality blameless

what are the number of your Jfets and the value of the capacitor in the tone area? do you have pcb? i want to try this .

PCB with two 1MX2 potentiometer to adjust the treble and bass

thanks for the layout,so your two 1Meg pots are Linear type and wired?

two 1Meg pots are Linear （X ）

I see the place for the pots on the PCB, but I don't see any pots on the schematic or the built prototype.

I can see atleast 5 capacitors in the signal path.

with reference to the schematics, where the pots should be tapped and what fixed resistors are going to be replaced?
