After emailing the tubestore guy, he said that the 5881's have a plate voltage of 400 V which is alot below the Mark IV's rating of around 470 V. However, I have heard that the original tungsol 5881's were often used in fender amps that had a higher plate voltage than the tube did, and with good results. It says in the Mk4 manual that 5881's are ok to put in all slots but I was wondering if tungsol's version are an exception that has lower plate voltage than other 5881 brands.

-Would reissue Tungsol 5881's work in a mark IV?

isn't 5881 another name for 6L6? because the mark IV comes stock with 6L6's.

The 5881 is a 6L6 TYPE, like how 12AT7's are similar to 12AX7's. The 5881 has a shorter bottle and sweeter sound than a 6L6.
Then there's this band called Slice The Cake...

Bunch of faggots putting random riffs together and calling it "progressive" deathcore.
Stupid name.
Probably picked "for teh lulz"
