MULLARD 12AT7WA NOS UK MADE Valve Tube. These are the best! Superb sounding double triode. Has slightly lower gain which may not even be noticed. In most cases will replace the hard to find and expensive 12AX7/ECC83.

I have for sale a yellow print Mullard ECC 83 pre amp valve in good working condition. I have tested this valve in a guitar amplifier, and it has good gain and sound.

Price is for a matched pair. 10 pairs available.

These are new production by New Sensor. We were shocked at how good these re-issues are. Try them in your classic guitar amplifier as well, for that thick 60s sound with fast attack and decay. Does it approach the original Mullard in sound?.
