This curcuit here is a regulated power supply. It’s made using linear regulators 7815 and 7915 for positive and negative voltages. It’s perfectly suitable for driving a preamplifier, tone corrections and anything else that runs on these voltages. It’s current limit is 500mA because the regulators are without a heatsink, otherwise with a heatsink max current is 1.5A. You can swap the regulators for higher or lower voltages – they are interchangable.
This is the top overlay layer. The dimensions are 42mmX83mm. The connectors can be a pcb block type or others with a distance of 3.96mm between pins. The regulators are in TO-220 package. All diodes are in DO-41 package and all ceramic capacitors are with 5mm distance between pins. The large electrolytic capacitors are with 7mm distance between pins and are 13mmX25mm in size. The small ones are 5mmX11mm in size.
