Overall, I’d say go the commercial power supply route because it’s about the same price, will last for a long time (rigs come and go, but power supplies have a habit of sticking around), it’s safer, and it’s a lot less trouble. Heater voltages are supplied directly from the 6. Overview This is a guide for building a DIY power supply/regulator for powering a Raspberry Pi and a USB audio output interface. There are hundreds of pages of Tube amp information on my library page. Order Now! Test and Measurement ship same day. Symbol and associated notation of op-amp The power supply voltages VCC and VEE power the operational amplifier and in general define the output voltage range of the amplifier. There is always some voltage drop so the power supply rails will be at least +/-15V in this case.
