Lightbulb Hello from Chicago...

Greetings all! My name is Steve. I'm writing this from downtown Chicago, IL, and I'm currently a Junior at Columbia College studying Film with a concentration in Producing. My other passion is hollow-state electronics, vintage radio, audio, and vinyl.

I work on projects when I have time and have even begun to design some amps myself (the one I'm currently designing is an 808 SE amp with 6SN7/ 3C24 as input/ driver) and have attached some photos of my work.

Glad to be hear, can't wait to be more involved as time progresses.

-Steve

Thanks to both of you! Sure, I can post some more photos later tonight of my phono stage.

It's a 6SL7–>6SN7 with 255V B+ regulated by 0A2/ OB2.

Attached are more pics of the phono stage. I based the design off this:
Jeremy's Tube RIAA Phono Preamp

It has a hum issue right now related to the filter cap, which I'm going to be replacing. I know the "rats nest" isn't as neat as it could be.

This thing is LOUD. I actually can't believe how much gain I get out of it.
