Universal Power Supply PCB - Page 6

Peter,

I'm thinkning of using an MUR3020, MSRF860 or MUR1520 with your rectifier boards for a balanced F5. What heatsinking do you use with these pieces?

Peter,

for R2/R4, is there a formula to calculate the value needed for a certain output voltage?

thanks

Which regulator you have in mind?

Peter,

Need a power supply board for Pass F5 build. Let me know where to order and how to order.

Thanks

Hi Peter.

I wish to use my universal PCB I purchased a while back from you to provide 24V for a Pass Labs B1 buffer.

R1 = 240R
R2 = 5R adjustable

I'm using Black Gate Standard 1000uF/50V for the main PSU caps either side of the LM317 on your board.

Do I need to bother with C1/C2/C5 in your opinion?

Many thanks!

I wouldn't bother with bypasses on main caps but would probably install 10uF cap across adjustable resistor.

Great - I'll do that! Thanks Peter much appreciated

P.S. Sorry knew there was something else! Peter do you prefer using a CT transformer and a pair of diodes with your PSU board, or a non CT transformer and 4 rectifying diodes? Which is meant to be the best? Thanks

are these pc boards still available?
where can they be purchased?
thanks,

I just run out of therm few days ago. Might get more in a future though.
