Very good power supply. Adjustment is stable. Almost no heat dissipation with the right transformer.

Great PSU
It works perfect!
This unit replace an old psu with the classic DC regulators LM317 / LM337.
Somebody here at reviews ask if can works as symmetrical + -v power supply. The answer is absolutely YES!
Works for me exactly as i was need. With AC 10V in every side, i have exactly + - 7.5 V OUTPUT!
The only thing you MUST do is to put a jumper from - to + exactly in the middle of the board (at output side), and grounding this point!
Also, no ripple, and imidiatly you can listen your difference from your old power supply!
Thank you Audiophonics for your products!
