The two pics above show the board populated with parts for both the fixed bias version
and the cathode biased version. You can buy the blank boards and assemble the VVR
with parts you obtain yourself or you can purchase a preassembled board. I do not sell a
kit with board and parts for you to assemble yourself. The pot and mosfet are not
installed on the board so that you can install the board, pot and mosfet in different
locations within the amp. If you decide to install it as one unit you will have to mount and
solder the pot and mosfet onto the board.
The preassembled kit includes the populated board, a dual pot or single pot (depending
on the version you ordered), the power mosfet and an insulator to insulate the mosfet
from the chassis or heat sink.
