Default Yep

Yep, if you use the 0-220V primary the secondary is 2X37 and if u use the 0-230V you have 2X34V (unloaded). This was a custom job.

I think you mean 2x34VAC at 1x230VAC and 2x37V at 1x230V

Sorry Panos. These are 5 to 6 VDC lower, than the one I need...

Default My mistake

O.K, but just to clarify things on my side as I did not put it right the first time. I mean that the primary uses 3 cables, 0-220-230 so if you have 220V in your plugs (as I have) if you connect the 0-230 primary it gives you 2X34 if you connect the 0-220V it gives you 2X36 output. (just measured it)

Regards,

Panos

Sorry but still 4 VAC (=5.6 VDC) below on each rail. I need +/- 55 VDC on each rail to match the other amps in bridged configuration!

Unfortunately the toroids I can source are 46VAC...

Anyway, hope you find'em soon.

Cheers

Andrea

Panos, are you willing to trade it with something (BJTs, caps, etc) ?

Cheers

Andrea

Default why not?

just state what you got in mind and maybe we can work it out. Thogh keep in mind its heavy enough and this means that postage will possibly be a bit "heavy" too.

Regards,

Panos
