**SOLD 3/15/2021**
I built this phono stage, based on the September 9, 2007 article in Tube Cad Journal. It works, but, to my ear is very bright sounding.
AD797 IC’s + EH 6922 tubes. I designed pcb’s for phono and power supply: phono board has some upright resistors as I neglected to remember that for equalization it took a couple in series for the correct value, the power supply board has the +15V regulator off board, as it required a heatsink larger than the space I allowed due to the heaters running on it. There is also an off board 12V regulator for the power switch light only.
The case is a beautiful brushed aluminum item, 12.5” x 9.5” x 3.5”.
Offered for $25 + shipping (U.S. only)
Send a PM if you would like this. Thanks.
