Power xfmr around 300vdc when rectified?
I wanna run some EL84's at about 300v and have at least 90ma for them, and 10 ma for the udder stuff.  
Hammond is too much voltage and no copper strap, Allen is too high a voltage, Fender's (Blues Jr?) pp el84 pst is only 68 ma.(Any comments on this xfmr?)  
Has any one any hint at where I might find the above 300v, 100ma beast?  
Thanks  
Dan

So you are going for about 30 watts? PT from commercial amps of similar size ought to work. PV Classic 30 comes to mind (320v), or the Crate ones.

Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

if you don't mind running two xfmrs (assuming you are not using a tube rectifier) 230V 100ma xfrmrs are only $15, or 190mA for $20, and will bridge rectify to about 320V. A seperate filament xfmr is also cheap...

Re: Power xfmr around 300vdc ,Follow up quest
Again, I appreciate both replies.  
 
The multi-transformer solution isn't practical for this app, but I appreciate the low $ idea.  
 
My follow up question is: where can I buy a Peavy Classic 30 power transformer for the least?  
 
Thanks
