Yeah, a real PIA if over 10uF too, altho the range is getting bigger
I got curious about what's now available in the IXYS block bridges - on Mouser, they show stocks of most reasonable sized ones 12 - 25A about U$20+ (these are the FRED diode bridges, not the basic epitaxial - VBE not VBO) - the ON Semi MSR1560G, on the other hand, are less than U$2 ea

Hi Pico, have you considered these guys? Toroidal transformers AUDIO GRADE - Shop Toroidy.pl I expect they customise but not sure.
Do you know what is the shipping cost to Melbourne? I am tempted to a couple, but was thinking 600VA min. Your idea is good in having two secondaries. They can be re-purposed if required. I need to start stripping amps in future, but they are all so special, every time I think about it hurts my brain deciding which one

.. I meant to add -
I was poking around Alixpress last night and came across some neat products that combined Soft Start and DC traps - included small transformers rather than the usual resistor divider/cap system - of interest?
Do they provide circuit diagram?
I'll see how the simple passive thermistor goes, but I like the idea in principle.

Yes I checked them out but I didn't get a quote for a custom made transformer. The off the shelf products didn't meet my requirements.
A transformer is basically for life so I feel it's a good investment to get exactly what you want.
Yes I know, it makes sense.
