Schiit Lyr Tube Rollers

    My say 7316/ECC186 on the tubes and on the original boxes

    I’ll look for some data as well, I know that Brent Jessee audiotubes.com lists them in the 12au7 page http://www.audiotubes.com/12au7.htm

    Probably because their original intended use mean they were pin and voltage compatible. Duncan's lists them as different rating.


    If anyone has a pair and a multimeter, can you check the heater current draw?
  4. AuditoryCanvas
    Yeah, that doesn't mean anything. He lists a lot of tube variants on the 12at7, 12ax7, and 12au7 pages - some of them are 450ma, and some are 600ma. Just having the same pinout doesn't mean they're compatible with amps that have a heater current limit like the mj2 and Lyr 2.

    I made a chart a while back for the 12at7 variants. I'll dig it up now.

    Here's that chart I had started making. Didn't get as far as the 12au7 variants.

    12at7 - 300ma
    12au7 - 300ma
    12ax7/ecc83 - 300ma
    6201 - 300ma
    7062/e180cc - 400ma
    7025 - 300ma
    7728 - 300ma
    7729 - 300ma
    6681 - 300ma
    5751 - 350ma
    6211- 300ma
    6679 - 300ma


    12az7 - 450ma
    12ad7 - 450ma
    6965 - 450ma
    6414 - 450ma
    6829 - 450ma
    E80CC - 600ma

    I can check when I get them. Isn't it kind of difficult to hook up in series to pin 9?

    The above post was not ment too upset you. I was simply saying that on his website he list the 7316 in the 12au7 family of tubes and agreeing with you in wanting to find more information on the 7316 tubes to make sure I don’t damage my MJ2. As I am still very new to tubes, started with tubes in February of this year. I am using the information I have been getting from fellow members to find and purchase some great tubes for my MJ2, as I have been “bit” by the “Tube Bug” A lot of the information you have posted back starting towards the end of July 2018 including your list has really helped me.

    Thank you for the list, when I was going back through reading the thread, I came across your list and made a copy of it. The list you made has very helpful and valuable information. As mentioned above I was going back through the thread reading up on the 12at7 family of tubes. I wanted to find some good recommendations for my MJ2. Using the information you and several other members have posted to make a list of 12at7 family tubes I want to try!

    When I get them I'll bend the pin on an extra socket saver and check. I can't think of a better way to measure.

    The plate current, plate voltage, and amplification factor are different:

    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.
