Tung-Sol / Chatham/ The 2399 are mostly labelled Chatham. I have white and yellow labelled ones

 

 

Some are clear tops, some are like the ones shown above with the top getter

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.

yeah 2399 is the same as 5998. 5998A is way different (similar to 7236 but theres a few differences as well).  

 

I think tung sol made all the 5998's.

I know this thread already has 767 posts, but we're going in circles here.  All the answers to the last 50 questions appear earlier in this thread.

Yes, it's getting worse on head-fi. People don't want to learn it seems. Sometimes I spend 4 days reading threads with multiple hundred pages. I take notes and learn, but hey, who am I smily_headphones1.gif

As it relates to the 2399, I'm not sure it's ever been established that its completely identical to the 5998 electrically. It's undoubtedly some slight tweak or variant of the 5998, and the looks are quite similar or course, but since I have never seen a data sheet on the 2399, not sure what exactly its specs are.

I also have tubes marked 6520 that appear to be 5998's internally even though 6520 is supposed to be an identical designation for the 6AS7G.

I'm sure Tung Sol had its reasons for all this, but its hard to decipher 50 years on.
