Hello. I have build about three or four preamplifiers during last two years. I am tired of expense and trouble of building, basically, the same power supplies. I decided to make separate one that can be used for different units. I bought on auction site Sony single ended amplifier power supply. I will replace capacitors with pio ones, install choke and two regulated heater supplies. I have a few questions
-what should be done in general to make it a great power supply
- any chance for 12 volts heater supply
-what is a purpose of T1 transformer
