Default Power transformer question

I need a power transformer with a 360-0-360 Hv @ 260 ma and 5v@2amps and 6.3v c.t. @8 amps. I can't seem to find one with 8 amps @ 6.3 volts. Each el34 needs 1.5amps X 4 = 6 plus 3- 12ax7 @ .3 amps =.9 plus ef86@.2 X4=.8 total = 7.7 amps. I've tried hammond. Any ideas. I was going to rewind the old one but that would cost $700 or more!

Do you have room for a separate filament transformer?
Be sure your foil hat has a good low impedance ground.

Not really. Its a leak amp from 1961. I was going to get the origional rewound but it would cost $700 to 1500. Then I was going to put a hammond transformer in but couldn't find one. The total current draw is 260ma so I would need a transformer with 260ma @ 720(360-ct-360) right? This is only a 50watt stereo amp(25w/ch).

Email Edcor. They will build one to your spec for an extra $20 design fee. There prices were better than Hammond even with the design fee factored in. http://www.edcorusa.com/home.html
