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

*If you’ve seen previous versions of this preamp listed here, they did not have the tube and coupling capacitor upgrades.  

I used premium Hammond power transformers, upgraded all the electrolytic capacitors to Nichicon, upgraded all six of the coupling capacitors to Sonicaps and I used solid core silver wire in Teflon (thin yellow wire) for the input and output signal. 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 matched pair of JJ Gold Pin 12AX7 tubes that sound amazing in this preamp along with the tube dampeners pictured. I’ll also include an IEC power cord and the original parts that I didn’t use.  

It is modeled after the classic Shure M-65 phono preamp with 48db of gain. It works with MM or High Output MC cartridges (~2.0mV or higher) with standard 47k Ohm loading. The little switch on the rear is for lifting the ground if you have issues with hum. Its dimensions are 12” wide, 8” deep and 5” tall. There is also a 6” by 6” piece of dampening material on the underside of the top cover to reduce chassis vibrations.  *Do not operate with the cover off. Lethal voltages are present and can be very dangerous!  

My price includes everything listed above. No PayPal fees. Let me know if you have any questions.
