This listing is for a Mullard 191 B81, 12AX7/ECC83 preamp tube. I unpacked a few of them today. I’ll be listing one more vintage Mullard because the third one was bad. This is an early Mullard. This is a long plate tube. This tube tested good with near perfect balance. For more vintage tubes check my other listings. Feel free to ask any questions that you have or to shoot me an offer.
