Hi All,
I recently purchased a Reduction phono pre from an estate. The kit was completed (minus the base), but the owner passed away leaving no documentation as to the build. Is it possible to get a copy of the Reduction assembly manual? It appears from a quick browse here that the owner had marked all of the test points on the bottom of the unit. I took a chance and fired it up on arrival, and the gain stage is working fine with no noise and appropriate output. The RIAA portion is skewed somehow, and the test/checkout procedures should provide some help with getting it dialed in. I have attached some photos, so any input the group would care to pass along would be great. As for me, I'm not new to tube gear, I've built tube-based kits before, and am familiar with safety protocols for working on high voltage tube equipment. I have a few good multimeters, and a scope that I'm trying to get set up (no signal generator yet). I consider myself to be a novice hobbyist with a reasonable level of experience (kit builds, recaps, etc). Thanks all!
Jaybird.
