@jb77 look at last pic, right tube, Looks like a smudged R Mitcham or possibly a B? Mullard. Hope you don't have a $200 plus max bid on these!

So there is a 1B that is legible (highlighted in yellow) also looks like a B before the 1B (red circle around the B) and there is some code above the 1B that is not legible. (Circled in red)

Heard a couple people mention these tubes, @bcowen and somebody else. No experience with these.

I have some, as well as some Sylvania military labels. Even have some RCA 12AU7A's dual labeled as 6680's. How many friggin' numbers can they apply to the same tube? Sheez. :sweat: Unfortunately, I can't offer anything on how any of them sound. I bought all these a long time ago, and more than likely they got a 'meh' assignment compared to what I *was* using at the time in whatever component I was using them in back then. IIRC, the memory is the first thing to go...or do I have that wrong? :hushed:

Ok cool. Thought you really liked the RCA's but as you said, you don't experience with this particular.

I wrote about them on page 1355, Post #20315 of 21276. I haven't listened to them since, but are a good tube that can be had for under $30/pr. The RCA 6201s are also quite nice IIRC.

Ahhh….the 5963's NOT good for rock? Looks like I'll be dumping these then. :slight_smile:

How many back-up pairs of your favorite tubes is too many? I'm asking for a friend... :stuck_out_tongue_winking_eye:

Only pair of backups I have are for my two top tubes, and one of those pairs was only bought because of an opportunity too good to pass on. A lot fo the tubes I love are rated for 10,000 hours...I can't honestly ever see me needing a backup. Unless of course I do what I did with one of my 6201 triples, and turn it into a vacuumless white top by being too forceful pulling it out of a tight socket...
