Pars Posted May 7 Report Share Posted May 7 Most of them don't seem to want to deal with small quantities, and if they do, the price is insane (~$500 for 1 piece, Toroid Inc.). I checked Bridgeport Magnetics, I think they aren't interested in 1-2 pieces. Others won't sell to individuals, only businesses. I'm guessing Plitron is in that boat as well, or would be insanely priced. Antek doesn't do custom, so it looks like I may wind up with 3 Antek transformers for this project. I think that is who Kevin is using as well, but I'll let him pipe up if he wants to. 1 Quote Link to comment Share on other sites More sharing options...
dsavitsk Posted May 8 Report Share Posted May 8 https://sklep.toroidy.pl/en_US/index I've not used them so I don't know the quality, but it's another option. Also, they're expensive but I still like the lundahl power transformers, particularly for use close to a circuit. Just be aware of their weird way of stating specs. 1 Quote Link to comment Share on other sites More sharing options...
jokerman777 Posted May 8 Report Share Posted May 8 Thanks for the info! Yes I used Toroid Inc once a few years back and I think it was very pricy for what I asked for - I think their one-off pricing is based on designing and making initial prototypes for businesses, which is understandable. I been using Antek whenever something off-the-shelf fits the need, unfortunately just not for a T2. Guess I will reach out to toroidy and mueller-rondo in EU for a quote then. Tricky part is I already got the chassis and I think Kevin designed them for the SumR ones originally where the diameter of each trafo can't really exceed 3.6", probably pretty marginal for their ratings and I'd need to spec that too, this might further reduce my options. (no lundahl, EI, C core etc..) btw I contacted Toroidy once for something else and I got the impression that they don't have 115V or dual primary winding trafos in stock in general.

MLA Posted May 8 Report Share Posted May 8 Toroidy will do whatever you need in my experience (including dual primary); anything T2 will be custom spec anyway.Ā Ā Mueller-Rondo lets you specify the exact diameter when you place an order, so that's quite helpful. The larger Mueller-Rondo (think 300VA) have a bit more mechnical hum than the corresponding Toroidy's (have built T2 psus with trafos from both). Not a dealbreaker if you're not sitting absolutely next to the psu box. Also, if you go with 3 trafos (I think that's what's in Kevin's original chassis?) I think if you spread the load none of them needs to be more than 150VA each, which should sort that problem.Ā Ā Ā Ā Quote Link to comment Share on other sites More sharing options...

Craig Sawyers Posted July 27 Report Share Posted July 27 (edited) ONSemi. Abandon all hope for the next production batches. Mouser says "758 Expected 12-Dec-23", but that alas for the hated semiconductor supplier, can usually be taken with sizeable a pinch of salt. Farnell says 249 will be delivered to them on 26th Jan 24. RS says 21st Feb 24 See what I mean about pinch of salt? Stock, when ONSemi finally supply a few thousand will disappear pretty darned quick as manufacturers hoover up stock for their production. Manufactured in China, like just about every semiconductor I've bought in recent times. Edited July 27 by Craig Sawyers 2 Quote Link to comment Share on other sites More sharing options...

bdinnev Posted August 2 Report Share Posted August 2 (edited) That does not appear to be the same switch - the C&K is rated at 5A, not 6A, and the writing for the ON / ON is orientated differently.
