Yes, Mouser also has them for 20 iirc.
Might be the way to go.

Yes, 6 layer, with 50 ohms impedance between the top two and bottom two.

Well, I guess everybody has gone, but linear circuit design is still chugging along. I'm back to fixing and upgrading my Linn Sondek phono turntable drive system, (I finally gave up and bought a new drive board from Linn), and am contemplating changing the MC cartridge that I am using. The one in the arm now is OK, but after hearing a really nice (unfortunately very expensive) setup that Constellation had at RMAF, I thought it might be time for a sonic upgrade. Vinyl records are certainly alive and available at these hi end shows, and they give a constant record as to how digital playback is doing compared to it. You still have a ways to go guys! '-)
