hi everyone
Having a sort through my collection of bits and bobs and came across a couple of 24v toroidal tx's i'd bought of ebay. These were mistakenly listed as having dual primarys, but actually only have a 110v primary and 2 x 24v secondarys. They cost next to nothing so I didn't kick up a fuss as they were being sold as part of a deseased grandfathers lot. Anyway, was wondering what to do with them, apart from possibly using them in reverse in some valve project perhaps, but then I thought that I could possibly use them to make a variable dual rail psu.
Would it be ok to connect the primarys of the 2 tx's in series for 220/240 v and then parallel up the secondarys of both tx's (after connecing the 2 x 24v in series on each tx)?
I then found this schematic
http://sound.westhost.com/project44.h
Seems pretty simple. The idea is to make this without spending a bean as I've probably got all the bits i need already and have a 25v panel meter and loads of old cases i can recycle.
Just wondered what your thoughts were?
cheers
