Custom Design Tube Phono Preamp. Shure M65.

Custom Phono Preamp Modeled Shure M-65 with Tubes and Upgrades! 

Hello. I built this vacuum tube phono preamp because I was disappointed with all of the sub $2000 phono preamps I’ve tried lately. They all sound the same. Just blah. No real definition or imaging. Rolled off highs and lows. Just boring.    

I took a chance on this kit and used very good Hammond power transformers and upgraded all the electrolytic capacitors to Nichicon high quality ones. I am blown away on how good it sounds! Now there is imaging, high frequency definition, bass depth and control and that midrange warmth I have been yearning for. I'll include a new pair of Sovtek 12AX7LPS tubes with dampeners as they sound excellent in this circuit. I’ll also include an IEC power cord. 

It is modeled after the Shure M-65 with 48db of gain. It works with MM cartridges with standard 47k Ohm loading. The little switch by the power inlet lets you lift the ground if you have any issues with hum. Its dimensions are 12” wide, 8” deep and 5” tall. *Do not operate with the cover off. 

I've built 3 of these, now and sold the other two to very happy customers. This will be it for now. Not building any more at this time. My asking price includes the preamp, tubes, power cord and FedEx shipping. Let me know if you have any questions.
