  1. Hi audioguru, I just finished this PSU. It is working perfecly. I used your parts list. Thank you very much! Can I have one more question? I am going to use digital meter PM129A-1 as a Volt indicator. Not sure if I should set it up to 199.9 Volts permanently, or to switch between 19.99 V and 199.9V automaticaly. If I have 199.9 Volts permanently, will it be accurate enough? Thanks again for your efforts. Vaclav
  2. Thank you audioguru, btw the heatsink size is 16 x 10 x 4 cm (6.5 x 4 x 1.6 inch) probably not too much?
  3. Hi all, I have a heatsink available with 3 transistors 2N 3055 bolted on it. Can I use it for this project? I guess it can be only good to have 3 instead of 2 transistors. How about the resistors in the emitors, should the values be different? Thanks for advice Vaclav
  4. Thanks a lot for the quick response! How about LF356N? Vaclav
  5. Hi all, I am going to build this PSU. I cannot get any of the opamps mentioned in this forum (OPA445, MC34071AP, TLE2141CP) Can I use NE5534 instead? Thanks for advice. Vaclav
