Default What can I build with +/- 60v rails?

Hello!

A buddy of mine gave me a pair of plate amps with very nice transformers in them, they are 49v-0-49v and probably 200-300VA each.

Can an Aleph or some other Papa amp be run on +/- 60v? Or is there something else to consider?

Are there any major disadvantages to this? (other than more expensive capacitors?)

I am sorry, I did not see this was pass labs section and you were looking to build one class A amplifier.

No problem! It's a neat design... the modules are kinda expensive.

How about an Aleph 1.2? Real beast, runs on 60v rails.

I take that back. Just realized how undersized your transformers are for a 1.2

I don't think there is enough current capability in the transformers. They are 300va or so.

Are they 50-0-50, or are there actually two secondaries that you could run in parallel? 60V or so would be perfect for DeLite....

Or, do they have dual primaries that you could run in series to get 25-0-25?

Single 120v primary and 49-0-49 secondary. Not a dual secondary.

DeLite, although interesting, is completely impractical due to hot lightbulbs sticking out the top... Toddler-proof it isn't.

Treat it as an educational opportunity.

DeLite style amps can also be built with resistors on heat sinks, but they don't look as cool...

Hi,

How about the CAS-1 or 2?

There is a version of the F5 Turbo that could do that.
