Comments about Ruby ECC83 (12AX7A) Preamp Tube:
I was trying to replace the tube in my Marshall VS100R and first tried Groove Tubes 12AX7s. The GTs were too high gain, and the VS100 hummed a lot. I tried Electro Harmonix 12AX7/ECC83 and had the same thing. 12AY7 and 12AT7 were lower gain and less noise, but I lost top end distortion and bass. Because the Ruby Tubes are probably closer to what came stock, it renewed the sound of the amp, improved the sparkle of the clean, increased distortion on the back end, and did it without adding more hum (there is always a little as in most solid states). I would recommend these for anyone looking to make the amp sound new again.
