[QUOTE="Jaymzrock, post: 127859, member: 2998"] I bought a NOS JAN 5751 and it sh!t the bed within 20 minutes of play time. To add to it, it happened at my band's first show seconds after I took the amp off Standby to start the first song. Luckily I had a few spare 12AX7's and my multimeter handy (I troubleshot the power tubes first) But I just got two JJ 5751's in and put one in the PI this evening. That **** JAN cost me like 35 bucks give or take but hey, tubes right?! :roll: I did notice when I first got it that the pins had that rainbow-ish discoloration as if they had been exposed to extreme heat. I didn't think anything of it until after the fact. Still don't know if that was anything indicative. [/QUOTE]
