Well of course. I finally just left my mini grabber neg on ground and started pokin around. I knew R7 was tied to ground through C10, but it wasn't acting like it, so I started down that road, didn't take long after that.

What better way to check the Phono section than the Phase Linear FACTORY RIAA curve tracer. The actual unit used in the test department at the factory.

First impression, F*&^%$ quiet , like no background noise. It tested at 153MICRO volts on the left and 173 Microvolts on the right. If Jani did the A/B test between it and my Spec 1 , I don't know if I could tell the difference, and that's saying something.
Thanks Joe, your guidance created an even better pre than I could have, appreciate that. I'm sure Ken will too.


Kenny you're gonna love this..

The PL 3300 Series II preamplifier is going to be nice to use, Ken. For someone who has a full compliment of Phase Linear gear it goes without saying that it belongs in the stereo rack.

Lee: Another informative build and that Phase Linear RIAA Curve Tracer is a unique piece of test equipment. Most test equipment doesn't look as good as the component it is meant to test!
