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, upgraded all the electrolytic capacitors to Nichicon Audio grade ones and upgraded the input capacitors to the excellent Audyn Cap Plus model. 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 have now ordered a much more complex kit to build so I’m selling this to fund some of the new parts. I'll include a new pair of Chinese 12AX7 tubes with dampeners to get you started. I've had excellent results with the JJ Gold Pin tubes 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 or High Output MC cartridges. 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. Lethal voltages are present and can be very dangerous!
Let me know if you have any questions.
Questions for the seller
Does this have the same +3db bump at 10khz as the stock M65?
Good question. I do not sense any bump at that frequency. Sounds very linear to me.
