Have a look to this link

There is quite a number of altec/perleess schematics. Hope you find something useful. It should be a power amp. mono.

Ciao

I think it is pretty obvious looking at it that this amplifier was a DIY effort and not the product of some audio company. Looks nicely built though, too bad you have not got the supply that goes with it. The chassis box appears to be a bud box incidentally. I have seen a lot of home brew amplifiers in this neck of the woods over the years and some of them were built to very high standards.

Seems like a tube regulated power supply to me.

I don't believe it is a power supply, as I recall I used the same type of peerless output transformer in one of my long ago projects. The OD3 could be used for screen regulation if the amplifier is set up for tetrode mode operation. The driver topology is anyone's guess..

What is on the other end of the black cable which appears to be coming out of the chassis?

This looks like a monoblock amplifier. At first guess, I'd say that the black cable goes to an external power supply.

Please furnish photos of the underside.
