[0-30 Vdc Stabilized Power Supply]

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

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?

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

Thanks a lot for the quick response!

How about LF356N?

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.
