Description

This is an assembled and tested cascode CCS (Constant Current Source) for use as a plate or cathode load or in a power supply for a tube amplifier or preamp. You can find full details including measurements at http://www.pmillett.com/CCS.html. I have three versions of the CCS: JFET lower device, current adjustment range 0.2mA to 5mA Depletion MOSFET lower device, current adjustment range 2mA to 15mA Depletion MOSFET lower device, current adjustment range 5mA to 50mA You must specify which current range you need when you place the order. In addition if you tell me what current you want it set to, I will pre-set the current to your specified value when testing the CCS before shipment. Otherwise I will set it to a default current. Flat rate shipping via FedEx to US destinations is shown.
