It's unlikely that it contains PCBs in the caps or transformer. The caps should be DC electrolytics and they are PCB free.

My one and only "real" power supply, but it serves me very well.

SeanB:
This is one I put together around 20 odd years ago to give me an AC supply from 0-12VAC at 5A. Isolated output, using an old variac. Originally the variac was designed for 115VAC 400Hz use, with a 5A rating, but on 50Hz 12V is about the maximum I will give it as a supply.

Po6ept:
I have owned a pair of these Lambda LA-200 supplies for years.  I just picked up the Protek 303 at a hamfest on Saturday for $30.  It works well, but I would still like to have one dual-voltage supply.

madshaman:
It's probably not my *best* PSU, but it's my favourite and it gets used the most:
