Default Nice Gears.

For a first project, that is mighty fine work, congrats! Very impressive consruction and metal work.

Nice gears, how are they working out?
Here are my preamp gears. Other than needing a lot of force on the handle you are turning, and you needing to be careful about how far you turn them (and the direction), they work great.

Default Gears

The gears work very well. There is only a small abount of resistance required to turn the knob about equal to the resistance of the two pots together. It was a pain to get the alignment just right.

Igreen, those external gears look awsome.

Default Wow that is beautiful

Nice job!

It's great to see the power supply in its own "box", essentially.

Would you be willing to say more about the details? The transformer looks potted...very nice. Where did you get it? What voltage did you go with? What kind of posts and rca-s are those? Etc.

Again, congratulations!

The transformer is a Plitron 2x25 I got off ebay, the pots are PEC from digikey the post and rcas are from parts express.
Other than that it's a standard LM3886 kit from BrianGT.
