Depends on which data sheet you look at. This is GE's (one of TK's favorites) for a 12AU7:

The 7316 is commonly considered a direct 12AU7 sub. The heater current was in question (and a good question), but with that out of the way it looks like the tube is compatible enough to use as a sub without worry. ​

Though the GE is my favorite 12AU7, I got the 7316 in the LP, just remembered higher ma tubes would not make it past the protection circuit in the amp. So I`m guessing without looking at any chart it is a close enough to a standard 12AU7. Thanks for the chart and the GE call out both are appreciated.

Just got a dud tube from freaking Brent Jessee, square getter Brimar 12Au7, his 2,200-2,200 tube tested kinda close at 2,040-2,000.
His freaking 2,300-2,200 tube tested at 1,875-1,350 and is freaking NOISY. Calling for a return. Probably noisy from the 1,875-1,350 tube.
Fellas without tube testers, I strongly recommend having a calibrated decent tester. If there was no noise on this tube and a person without a tester bought these probably would be content with the nice testing numbers on this tube.
Don`t remember if I recommended a tester before so I included the warning.

Amazing. We don’t need no freakin Brent Jessie anyway. We got bangybang to take care of us all.
Here’s what I think. Someone ought to step up who has a good calibrated tester that wants to charge a nominal fee to test tubes for their fellow headfiers. Hell, I’d buy, have them shipped to the tester and pay for shipping back to me PLUS whatever it takes to take care of the “tester”

Unfortunately that's not me, I have to bum a ride to the USPS just to return these POS tubes. Can't drive for a while.

What's your min. good on the 752 for a 12AU7? 675 (at x2)?

The last tube I bought from him (and it's the last tube I'll buy from him) was a TungSol Mouse Ear 6SN7. My readings were way below what he'd advertised and what he'd marked on the tube -- both triodes were dead on the minimum good reading. Minimum good means it's pretty close to bad....

1,350 right on the minimum and microphonic too. This tube had 2,300-2,200 on the box. That low Gm on 1 triode is enough to make it very noisy on the LP.

My DAC is dead. No idea why. Don't have the cash to replace it

That's a total bummer. You don't happen to have a pair of closed cans you'd be willing to trade for a DAC?

Sadly the only cans I have are 400I's. Have been rocking them for a while. College kid life.

Looking in to that Massdrop DAC as a standby. The grace design one. Anyone heard it?

Tough week for HP users on this thread. Dead DAC. Dead HPs. dead tubes. And I had my laptop stolen out my car a few days ago.

I think Ripper has a pair of Mickey’s and Hello Kitty’s for under $500.

Hey Ive listened to the 400i’s, they are respectable!

Sorry, I already bought the Mickey's. I think the Hello Kitty's are still available but the earpads are like super greasy.

The grease is the latest in diy tech, it softens digital etch!
