Power Supply for Preamplifiers (Revision B) Posted by Circuit Diagram in Amplifier wiring diagrams Please Note: PCBs are available for this project. Click the image for details. Introduction. Power Supply for Preamplifiers (Revision A) – Circuit ... Figure 1 – Preamplifier Power Supply. If a single AC supply is connected between GND and AC2, the rectifier is a “full wave voltage doubler” type, and with an input of 16VAC will provide about 20V DC at a current of up to at least 100mA – this should be enough for the most power hungry preamp. Power Supply for Preamplifiers (Revision C) Preamps may in some cases use a simple regulator. With the supplies taken from the main amp power supply, this can be a problem if the main amp is of very high power. The supply voltage will be too high for 3 terminal regulator ICs, and they will fail. DRW 1409 1 FH71 STANDARD & STANDARD SENSITIVE ...
