The Boozhound Labs pre-amp I built needed a power supply. The basic option was just to use a basic “wall wart” DC power supply, but knew these were generally low quality, unregulated and quite noisy. Since pre-amp quality is pretty dependent upon power supply quality, I decided I wanted to use something better.
I found a project by AMB Labs for a Sigma 11 power supply. It’s a high-quality regulated single-rail power supply. I’d configure it for 24v.
Again, I used a case from Modushop and a rear panel from Schaeffer.
Here are the images of the completed build.
I wanted to replace my basic Pro-ject Phono Box preamp with something a little better. After reading through some threads on diyaudio.com I found a project for a JFET RIAA pre-amp from Boozhound Labs.
The kit came with a PCB and the parts required to populate it (including Russian PIO capacitors) but needed a power supply. I made that separately.
As with my Hypex Power Amp, I bought a case from Modushop and had a rear panel machined and engraved by Schaeffer.
Here are the pictures of the completed build.
I’m very happy with the result and the sound quality and have been using it with my Thorens TD-160 Super.
I wanted to new multi-channel amp to replace my previous Marantz MM9000 power amp. After reading various reviews on diyaudio.com I decided to use Hypex modules. Specifically, UcD180HG 180w amp modules along with Hypex’s SMPS power supply modules.
I used a chassis from Modushop and had a rear panel machined and printed by Schaeffer.
These are the images of the competed build.
Because the amps expect a balanced input I also needed to make some phono to XLR input cables.
I was very happy with the result though later replaced the front two channels with a tube amp as I found the sound a little too clinical.
