> secondary posts gives 6-8 volts AC at 3 Amps. That's what I was 
asking

Try looking at the hammond line @ hammondmfg.com look under classic 
tube transformers. They have specific filament xfers in the 3-8v @ up 
to 10amps. 

That or find any old peice of electronics that use vacuum tubes, the 
2ndaries always include a 6.3v filament winding capable of a couple of 
amps. 

If you decide to buy try angelainstruments.com, they have the best 
prices on hammond xfers Ive seen over the last 10 years.
