Commercial smps with 240v out

[poynton]

Hi.

If this has been covered before, my apologies. My search was not too thorough.


Is there a pre-made smps available with an output suitable for tube work i.e. in the range 250-300v Dc out with 110/240v in??

Failing that, can I 'piggy-back' an identical transformer in reverse across the secondary to give the HT output?

thanks

Only if the design is unregulated = no feedback.

sure u can use two transformers back to back.

There are a few smps i know of for valve pre-amplifiers.
