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
• Solid State 1
• Solid State 2
• Tubes 1
• Tubes 2

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.

Solid State 2

Schematics by Rainer zur Linde from his book "Build your own Audio Valve Amplifiers".
Output 190-320V 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.
