It only takes one noob to be suckered in by hype in threads such as this, then the new price has been set. The fact that they are expensive in turn generates more hype, tube vendors raise prices even further...... Mob mentality 101.

I would never post in a thread that's full of hype.

I got my tubes yesterday, 2x Chatham 6as7g, TS 7236, and Chatham 2399. Rolled in one of the 6as7gs and now on the 7236. Throughly enjoying them. Going to save the 2399/5998 last. If only I can do this at home... but the misses doesn't know about the tube amp/addiction. Sooo this is going to stay at work for the time being.

[size=11pt]I have  NOS quad sets of Chatham 6as7g tubes at $45! That was last year. The cheapest set was the 8 Philips NOS 6080 tubes at $27 last year as well. The most expensive are the Bendix graphite tubes and the only ones worth the high dollars in my opinion. I am thinking about getting another 6DJ8/6933 type of amp since I have very nice matched pairs that I paid about $20 now worth $350 these days.

There are 3 6520s in the batch....not easy to find. Shhhhh.
I'd like to get just one 6520, but not willing to pay 5998 prices.....so I wait.

I wonder why they are bidding $680 for 8 tubes that aren't even 2399/5998/421A. they're "normal" 6AS7G, sure they have the nice copper Chatham grids but are people that easily fooled? (I paid $20/tube for these a while ago)

But the 6520 is just a regular 6as7g, with the same specs. Shouldn't cost extra at all

 

[GrindingThud]

It has different voltage and better matched sections.  It's a 600V tube.

True that, but heater voltage is still 6.3

oh i got them from ebay, tube maze store, their stock changes all the time though, sometimes theres something good like these. 
 
and yeah chatham 2399 = tungsol 5998.

 

[mikek200]

Tnx Dubstep,
 
Please correct me if I'm wrong---Is the 2399,the same as the 5998,or,the 5998a?
One is made by IBM,the other by Tung-Sol-right?
 
Yes,Nikolay from Tube maze,has some pretty good stuff,,I've bought a few from him,and he's a pleasure to deal with.
Yesterday,I picked up a Tung-Sol 12au7 black plate..,if it's half as good as the 5998,I'll be  happy.
 
Mike

 

[EraserXIV]

My understanding is the 2399 is the same as the 5998, both made by Tung-Sol. Tung-Sol also made some 5998 which are branded by IBM, but are the same as any other 5998.
