This is a blank PCB to mount one or two snapmount electrolytic capacitors. Up to 35mm in diameter. The typical use is for power supply filter capacitors ... morein a tube amplifier or preamp project. I got tired of figuring out how to clamp or glue common snap-mount capacitors(designed for PCB mounting) in a tube amplifier chassis using point-to-point wiring. So. I designed this little PCB. The PCB has space for two caps. That can be used independently, or easily jumpered to connect them, in series. There are spots for bleeder resistors(or voltage equalizing resistors if the two caps are connected in series) that can accommodate 2W or small 5W resistors. It mounts to the chassis via 4 holes in the corner. Screws and standoffs are NOT included. For dimensions and more information refer to my web site: http:www.pmillett.com/ppdrv.htm#the Capboard This auction is for one PCB only. No parts or anything else is included. Photo of assembled PCB is for reference only! Will ship anywhere. Flat rate shipping is shown. Additional PCBs ship for free. Payment by PayPal on ly.
