4x DIY PCB - Cascode CCS (Constant Current Source)

Description: This is 4 pcs. blank PCBs to build a cascode CCS. The typical use is as a plate or cathode load tube amplifier or preamp project. The 4 individual boards are V-scored as part of a bigger panel and are easily snapped apart either before or after assembly. The CCS uses a TO-220 depletion MOSFET (upper device) and either another depletion MOSFET or a JFET (lower device). Note that the board uses surface mount components - they are parts that can be installed using a soldering iron (no buried pads so no reflow required). Details of the circuit can be found on my website at http://www.pmillett.com/CCS.html. This auction is for one panel - 4 PCBs - only, no parts or anything else is included. Photos of completed unit for reference only. Flat rate shipping via FedEx to US destinations is shown.
