The 12AX7 is the single most important signal preamp tube. PM tubes are built to the highest possible standard and have extra screening to eliminate microphony (squeal) and excessive white noise. The PM 12AX7HG (HIGH GAIN) will replace the same tube as the 12AX7A but is the choice if your amp needs a little extra punch. These tubes deliver up to 20% increased gain.
