Hi Guys,
I am building a 01A preamp based on Mr. Bartola's design 01a Preamp Gen2: Build Complete.
I plan on using a tube power supply using a 5Y3GT tube because I have stock of them. I understand the build and have all the parts however I am a bit lacking in confidence when I come to specifying the HT power supply transformer. I have developed a simulation using PSUD2 and would appreciate it if someone could look at it, critique it and give me some help on possible improvements and then assist with specifying the best transformer.
So far what I am thinking of is as follows:
Input: 0 210 220 230 240
Output: 135 0 135 30VA + 5V 3A
Power supply
Chart
Help would be greatly appreciated!
