    Thanks SO.
     
    I am going to draft a driver and power tubes list next.

    That is a very helpful chart. Thanks for creating it!

    I'm going to feel guilty after you put the work in, but I would like to offer some corrections:
     
    - The GZ33/37 is a yes for both power tubes.  They are more than up to the task and have almost the same current output ability as the 3DG4.
    - The 5U8C is also more than up to the task for both power tubes, it has the highest current capability of any single rectifier I know of.  It is not even breaking a sweat in this amp, and that is really saying something.
    - The 5AU4 is also quite safe to use with 6AS7G tubes provided you are using the older version of the tube with the wider and longer plates.  It appears only GE manufactured them, and they are easy to spot because their glass envelope and base are really big.  They dwarf most straight bottle rectifier tubes.

    Eek! I've been using the 596 with an GE 6AS7GA and an RCA 6AS7G for about a year. I hope I'm not ruining the amp. It sounds excellent though.

    No, you're just fine.  Glenn said so himself.  All you are doing is shortening the life of the 596 tube itself by an inconsequential amount.

    USAF-596, probably a service life of 5 years instead of 10 years he reported with the 596/6AS7G combo...

    Okay, thanks, SO and Xc255. I took my headphones off for one minute, saw the chart and panicked. I am now calm--and back to my headphones. :)
     
  13. Silent One
    You're most welcome...happy listening. I can't wait to return to the listening room @ midnight!
