This is my New Second version of the Nelson Pass Bride of Zen preamp, in custom Cascode config.

Ideal layout especially when using multiple Channels, All Power on one end, All audio paths on the other end. 

64mm x 203mm

Has dedicated on board regulation per channel.

Off board Transformer and rectifier must be used, can also use extra CRC Cap filter board if desired.

Set of two blank PCB boards for sale

*Built Board Pics are assembled examples only.

I will combine orders, ask me about other spare boards I have if you like.

I will provide Parts list BOM and schematic Via Email and printed form.

Please Send me your Email address. 

You won't find the BOZ in Cascode anywhere else that I know of.
I've made them mono board style with separate power supplies per board,
And capable of very high bias.
This is one of the best sounding preamps I've ever had, beats my class A valve pre for rich tube like tone with the benefits of solid state Mosfet.
