It's such a completely obscure requirement I doubt anyone has?. You also don't give much information, such as if it's AC or DC? (presumably DC?, as it's such an unusual voltage), and what current is required?, for that matter what it's for?.
The PS is for a Nixie Tube Clock. These "tubes" need around 170-180vdc to operate. Instead of using transformers, I saw someone using a Switchmode to up there 9vdc that powers the TTL's (+5v) to 180vdc @ 2ma to power the tubes. This would be smaller package than 2x 120vac transformers.
