HI
I have a DIY SVT "fridgerator" as a main bass amp. How ever, I'm going to make a little bassamp for small gigs with that Cold amp pack.

It'll have an SVT-type tube pre, because I like the way it sounds.
I try to make the amp as light as possible, so I first try not to use transformers.
Need the most simple way to convert that +/- 60 VDC to around 250-300 VDC for the 12DW7 anodes (SVT-type pre). It only takes 20-40 mA. Is there one chip that makes it? The filament voltage can be taken from that PSU.
Thanks.
