I've been looking for a suitable transformer for building a 300W PSU
0-30V @ 0-10A. My 2.5A one just isn't cutting it anymore. I already
have everything I need with the exception of the transformer.
I was wondering if older A/V receivers would be a good place to
scrounge a transformer. There's a couple of pawnshops in town that
sell old ones for anywhere from $20 bucks and up. How could I tell
without opening up and measuring the secondary of the transformer what
the secondary is. I know the question is a bit weird but I'm guessing
an audiophile would know what a typical secondary is. What are good
models if any that I'm likely to have success?
Ideally I would like a 25.2V (stancor makes these) secondary but this
is probably reaching but is a 28VAC secondary common?
Another alternative is to use two of the seventy watt Flyback
transformers I have to construct an interleaved flyback at 140w. Then
put a linear reg on the output to adjust the voltage down.
Any suggestions?
Thanks
