Rare indeed

It's not IBM, they were made for IBM. Or so I've been told. My 'knowledge' isn't mine, I have just borrowed it.

Any tube with lots of 9s on it were made for IBM computers.

Is this worth my $150 ?

Definitely not worth $150, or even close to it .. however, notice the double DD getters, these are some of the best GE 6AS7 tubes imo, and are my favorites in the 6AS7/6080 family which I have tried (this includes the 'famed' Bendix 6080 with graphite plates). There are two main variations of these I have found and own, one with double mica, and one with triple mica (which usually have copper support rod, and a slightly taller bottle). I like them equally - if I am not running my 6336 and 6528 outputs, I am generally running these.

$150 is in Aussie dollars. Is that still not worth it?

No.. not even remotely .. here.. this is worth it, and if I didn't already have a supply to last me the next two centuries, I would buy these myself.

Or, if you only need one in the amp you are running them in, you can get both flavors, although, I think they sound very similar, if not the same.

No worries. Not particularly wanting to buy those tubes because I don't use them. More of a sentimental value because I have work with IBM computers all my life. So it's a show piece on my desk if I do get them.

Show piece only - could go with something a lot cheaper still compared to those 6AS7 IBM tubes labeled as 5998.

Perhaps if you'd increase my salary to $0.36 per hour I'd send you one. Yes, I know that's a 2.5x increase, but you only get what you pay for.

Yes I need that badly because 5998 is my birthday.

You were born in May, 998? Damn. I thought *I* was old.

5th Sept 1998. You are old indeed if you can't work that out.

I am old, no doubt. And the 25 year-old you is hallucinating.
