F5 trafo

[bearwik]

Hi, I've got a pair of trafos labelled 600Va, 47 volt, can I use them for a pair of F5 amps?

You need a traffo with 2x18V secondaries.

Those are in Honey Badger range. Why not build one of those?

What suggested VA for a Pass F6 then??
Thanx

I'm getting ready to use 500VA, there is play room with the VA spec, it's the 18+18 volt secondaries that are needed

The Honey Badger looks integrering, I Will propably build onekligen when I'm donera with my F5 projekt. Thanks for your answers.

labelled 600Va, 47 volt

What voltage?
single secondary @ 47Vac
or
dual secondary @ 47Vac plus 47Vac
or
centre tapped @ 47-0-47Vac
or
centre tapped @ 23.5-0-23.5Vac = 47Vac centre tapped.

Tell us what you have !

The label says sec2 x 47 volt. Is that enough info? Otherwise I can take a picture of the label. I´m a beginner at this stuff.

"The Honey Badger looks integrering"
It should have spelled "interesting", damn autocorrect...

Like Russellc I used 500VA with the supply shared by both channels.

2 x 47volt = dual secondary and that when rectified will give supply rails of approx +-68Vdc

Definitely NOT for ClassA.
Although one secondary could supply a single rail ClassA. I think there is a Pass amp that uses near 60Vdc.

Would suit a very powerful ClassAB, or switching amplifier.
