To make a real "Reference Project" you should think about each stage from the start to the end.
So let´s look to the start...

The Main Transformer

Custom build on double C-Cores

Input:

115V
0
0
115V

So 115V & 230 V is possible.


Output:

200V
150V
120V
0 - CT
120V
150V
200V

for various B+ of a tube output stage, including a center tap for a tube rectifier.

20V

12V

salas shunt regulator input for the -5V line of the TDA1541A

12V

salas shunt regulator input for the +5V line of the TDA1541A

12V

salas shunt regulator input for the +5V line of additional digital parts
