For lower power projects like preamps, headphone amps, etc. I like to use power supplies with TO220 voltage regulators.
I designed a universal board for this.
To power a recently built OREAD, among other things, I had some new supply boards made and now have some spare boards for sale.
The board can be used with TO220 voltage regulators like LM317/337 and 78xx/79xx or others with the same pinout.
It also allows the use of: fuses, RC-snubbers for transformer secondary windings, rectifiers like 1N54xx for full 1.5A current, CRC filtering, suitable heatsink,
soft start for output voltage.
The circuit below shows values for +/-15 volts output. A BOM (example/proposal) will be sent to buyers via email.
Price for one Board: 5,80€
shipping inside EU: 9€ (I ship worldwide if you don't mind the shipping costs)
If interested: Email/PM me
