I just took delivery of a SUNYIMA EC42 SMPS transformer:

Because I still think it is worth investigating creating a few 100mA of tube HT from a chunky 12V heater power supply (also SMPS). Then I found this:
https://www.aliexpress.com/item/32969027567.html?spm=a2g0s.9042311.0.0.3da24c4dRb1Pdb
which is basically a kit to build pretty much what I am thinking of. it will need some mods to close the loop but it should be a good basis for experimentation.
Whilst looking around the same site I came across this:
https://www.aliexpress.com/item/32997695785.html?spm=a2g0o.productlist.0.0.3e1f4615NdABLp&algo_pvid=26739ab4-b507-42db-ada0-8d2fd48b55b2&algo_expid=26739ab4-b507-42db-ada0-8d2fd48b55b2-0&btsid=e0c38663-5fcf-48e7-acdc-78c4ed0993f6&ws_ab_test=searchweb0_0,searchweb201602_6,searchweb201603_55
which supposedly takes mains input and provides 265V dc at 150mA and 6.3V dc at 4.5 amps. I think I might buy one just to see how it is done.
Cheers
