Superphon Project
09/14/17 at 17:56:27
 
As luck would have it, I got my hands on a pre-amp that I sold about 35 years ago from a friend. It has actually survived a house fire, but due to some heat issues, I decided to gut it and start anew. Painting the chassis was simple enough, but I skipped the faceplate and rear panel, which I will decide on what I might do in the end. I will be adding new circuitry in the form of a buffer amp, using with it a set of mono volume controls. I have done this before with great results. We will see where this leads.

I'm not familiar with it, but that does sound like a neat history.

LR,

 Superphon may have been the predecessor to PS Audio. Stan Warren, and that other guy, um what's his name 0), Paul something. Anyway, they worked together a number of years. These units had a separate chassis for the transformer, and I discovered that the DC portion of the power supply ran at 24 volts. It *was* quite robust. There was too much trouble to deal with it all, and after looking over the circuit boards, I decided that they weren't the best there was to begin with.

Evenin' Folks,

A good start for sizing, drilling a bunch of new holes and some layout. Got a long way to go.

Just about there. Installed the tube buffer and a different sort of animal. An AR TDS202 module. Basically, it is a set of output transformers and a couple of filters designed to be a sort of loudness circuit. I found a small black enclosure to mount it in, and will be doing some listening soon.
