[QUOTE="ludo, post: 44216, member: 691"] Next step up from 225VA is 300VA IIRC. Bigger is better of course, until you have to pay for it. Sorry, off topic: Chipwelder, the choke for that thing is going to have to be laminated/gapped not so? Toroids don't like DC unless they have some very specific ferrite-like core (iron dust?). Maybe speak to Chris at CM Transformers in PtaW. He does one-off type things, but that would be one very strange core. Any specific reason to go with the choke in stead of the active (transistor based) current source? I think a couple of BJTs will be cheaper and smaller and easier...(?) [/QUOTE]
