VVR Tag Board????
I have a pdf layout for point to point fixed bias VVR in a Wreck Express clone. It requires NTE 2372, NTE 2973 Mosfets (I found on Ebay) and a dual 1Meg 1/2 Watt Linear pot to work. It works great in my Wreck clone. I'm cautious to post. What shall I do with it? Not looking to make any profit. Just trying to help others to "Make it Happen".

Go ahead and post! We've done a bit of work on the fixed bias VVR here. And in fact, Lou (jazzguitargimp) has made a very nice PCB for it.

Re: VVR Tag Board????
The added caps and resistors on input and volume pot are used to fix scratchy pots at low volume.....so they say.
I am not an electronics expert, I only wished that I had this layout years ago...so I made it myself.
Next, I think I'll try and fit the VVR circuit on the power supply board (next to the bias circuit). That would eliminate the added board.
Let the discussion begin.

I found the Mosfets on ebay. Dual gang pot at Amplified Parts.
I added a 2k2 resistor before pin7 on input tube. I believe this was done on Ingrid.
I moved a couple of terminals on VVR board and the size is a little different from the layout. Same exact circuit.
Always BIAS with VVR Pot at MAX!!!!
Enjoy.
