Title: 12AU7 SRPP circuit Preamp for sale
Post by Lon on 08/20/12 at 15:30:07

For sale is a "home-made" (not by me, but by another Central Texas resident) preamp built with the SRPP circuit utilizing two 12AU7 tubes.

I used this preamp in my main system for about 500 hours. I'd say its total fidelity is 85 percent or so of the CSP2's. It lacks a bit of resolution and a bit of the furthest reaches of both frequency extremes. The case is wooden, the transformer is torroidal, and there are three inputs (selector switch on the front) and a volume control (on the top).

This is available for 275 dollars including postage within the continental USA. SOLD TO CARY
