    Here is the working side of things. Three gain stages with passive RIAA.

    Well done with the nice and tidy looking construction!

    Several years back I built a Very Simple Phono Stage. I took my time doing it and am quite pleased with the results, but my construction looks no where as fabulous as yours.

    I cannot tell by the pic, what type of tube is this designed for?

    Beautiful work btw!

    I tweaked the power supply but it is basically a Juicy Music Tercel. Years ago I had an original Tercel and really liked it. It is very detailed with a touch of tubeness. Well I regretted selling it and when I wanted another, they were no longer in production. I contacted Mark Deneen of Juicy Music, and having seen some of my previous builds, he agreed to send me the schematic.

    The chassis is from China that I got off Ebay. I requested it come with no holes drilled, so I could customize it for my layout. Here is a picture before I did the tube cutouts. I used an Alps rotary on/off switch in place of what was originally designed for a volume pot.

    Your build quality is absolutely stunning. Great job.

    Also those are some serious cans for a phone stage.
