Regulated Power Supplies

Even if I do prefer classical supplies, regulated supplies can be helpful in some circuits like heaters, screens or bias.

Low Voltage Supplies

Such supplies are often realised with dedicated integrated circuits nowadays but it's still interesting to give a look at old designs to understand the basics.

A fixed supply of 6, 9 or 12V, max output 1A.

A variable supply 0-15V, max output 1A.

A fixed supply 53V, max output 2A.

Solid State 1

Schematics by Rainer zur Linde from his book "Build your own Audio Valve Amplifiers".
Output 10-350V up to 50mA.

Tubes 2

Main circuit

Schematics by Rainer zur Linde from his book "Build your own Audio Valve Amplifiers".
Output 60-400V up to 150mA. The second EL34 is optional for more output current.

Additional Stage

This second stage allows two indipendent positive voltages.
