No more big power supplies for preamps

Don't necessarily be fooled by full sized power supplies. I am aware that both Bryston and Pass, in the past, marketed a pre-amp and a phono stage, respectively, that initially had separate but small power supplies only to supplant them with the identical power supplies but housed in full size cases. The market was far more accepting of a half empty power supply case vs. a just right sized case. It just bugs me when I see the insides of a component that is half or more, air

That "air" may be serving a good purpose, namely preventing different parts of the power supply from interfering with each other. Here's shot of the inside of my preamp power supply, I purposely designed it to keep the B+ supply (front and right side) away from the two high amperage filament supplies (in the back). The B+ transformer and rectifier tube are on the top of the box, so not in the picture.

A "half full" chassis could be a very good sign and indicative of a simple straightforward circuit. You can have a robust power supply coupled with a simple circuit with fewer parts that are of exceptional quality.

Ait, nice job on the preamp! Love to see the rest of it.

Agree with Bill, it's attractive and looks well built.
Congratulations, I'm sure it sounds wonderful.
