I think that an external PCB is needed.

I'll start trying it on breadboard and if it works as intended I'll probably make a PCB.

I did use a dim bulb tester in line when I first tested the transformer before first plugging it into the board. The bulb never lit up at all and VAC outputs all seemed fine.
Very good advice though, and I will put the dim bulb safety factor back into the mains AC power supply line right away.

Thanks for the reminder.
Bill

I stumbled across this unit this morning. Has some interesting info at the design link on the page. Has anyone tried it?

Hey, "It's only money!" Right?

That's one reason I wanted someone else to try it.

Hi Dario ,

What about capacitors in your shunt reg ?

Thanks
Serge

Hi Serge,

the idea is to re-use the ones on board.

My kit arrived also (1.5 weeks from Singapore to the Netherlands).

I have some questions:

* The supplied resistors are 1% versions. I want to change them to a metal film 0.1%. Is that a good or bad idea?
* The smoothing capacitors (2200 uF) are made by Toshiba. No other markings on them. Should they be changed? Can any capacitors (like
10.000 uF, Philips or Panasonic) be used? The little ones (220 uF) are made by Nichecon FW types.
* I will replace the supplied L7812 by MC7812CTG
* The 100 nF capacitors are orange, drop type. No further markings. Also other capacitors are square, white or blue. No markings. Should or can they be replaced by sibatit capacitors?
* The 10 uF capacitors are gold marked, "W6C PET" marking. Good enough? Or tantalum is better?
* On the PCB I see some very small holes, and no marking on them. Are that VIA's to the other plane (bottom / top)
