Speakeasy - "Vintage Tube" Preamp

Speakeasy - 5-Pin Suitcase Power Supply

Speakeasy - "stage box" preamp

It's been a while since we had a Spaceman Effects pedal in the shop, but I'm excited to bring you all their new Atlas IV: Preamp Booster!! This one will find a spot on ANY pedalboard instantly - check out our demo and review!!

Recently my son has gotten more interested in music. A month or two ago, I helped him research and buy a small headphone amplifier for his desktop PC setup.

However, in addition to the amp, he wanted a vacuum tube preamp since he's seen the one I have for my PC (you can see part of it in the last pic) and wanted a similar configuration. :)

So I set about gathering some parts I had on hand to put one together for him. He selected the wood for the case from my stash, and the white aesthetic to match the rest of his PC setup. I used 2 6C4 tubes because I had them and they seemed like a fun choice for this.

Most of the work came in constructing the enclosure. I used my chop saw to cut pieces to length, then resawed them on my bandsaw so they were thinner. I then glued up the wooden box with some support blocks to increase the strength and give me somewhere to mount the metal plate that will hold the parts.

I'd recently scored a bunch of aluminum and steel sheet, so I used one of the aluminum plates to mount all the parts. The thicker plate was really nice to work and drill and allowed me to chamfor the holes so the wires won't scrape. Then I painted it up and mounted in the components.

This project involved a lot of 3D printing as well, all the transformer covers and the capacitor brackets were printed on my FlashForge 3. Boiled Linseed Oil was used on the wood for a natural finish, and the power light enclosure is an old glass bottle that I 3D printed a diffusion cap for.

Overall I'm really happy with this project, and so is my son who's been using it constantly over the Thanksgiving break. :)
