Linear power supply module

[Alan D]

Has anyone had any experience with these:

I normally build my PSU's from scratch, but thought I might try a couple of these for a pair of Temple Audio Monoblocks.

Any comments most welcome.

No experience of these particular modules Alan , however I've dealt with this Ebay seller ( sep-store ) on three different occasions and his srevice and goods have always been excellent . I just received one of his linear PSUs this morning and it's been powering my M2 Tech Young DAC all day without a hitch :)

Dunno,, Maybe it's good Maybe it's Not?.... Feeling Lucky ?
Personally I've tired of Chi Fi crap... having bought Too Many 'bargains' over the years.

Looks perfectly good. I'd use big Panasonic or kendeil for the main caps and Cree or Qspeed diodes but other than that.

Thanks,

I think I will probably try them, was interested as they were not run of the mill 3 terminal regulator designs.
Need to source suitable transformers first, as for 18V output they require 20V+ secondary.

Thanks for component recommendations Simon.

It would appear these are adjustable "The output voltage can minute adjustment" can't see why you could not choose any voltage between 5 and 24v? from one module?

[Alan D]

The output is set by a reference zener diode which is specifically chosen for the desired output voltage.
I guess there is a little trimming feature for those of us with OCD that would like to read 18.000000000000000V on a meter!

But basically yes, the board can be used to make a psu with what ever output voltage you like by changing the transformer, zenor and it's series resistor.

Hi Alan. Did you go ahead with this ?
Thanks
