GB Thread

DCSTB Board $20
DCSTB Board $25
Transistor Kits for the DCG-3 and the DCSTB are available. Full kits are also available.
DCG-3 Transistor Kit $ 40 - includes matched transistors where needed.
DCG-3 Full Kit (includes transistor kit) $75


Note that DCSTB kits only cover half the board. Additionally, if you wish to run at a higher bias and only use one board, let me know and I can make some part substitutions.
DCSTB Transitor Kit $15
DCSTB Full Kit (includes Transistor Kit)$45
So order two if using Dual Mono.

DCFlexy Board
The DC Flexy is a companion rectification board for use with the Mini or in general. It can take four TO-220 diodes and a Mundorf four pin filter capacitor or any normal two pin capacitor by just deciding on which alternative pads to install the diodes.
