For those who have tried it, do you find that the Bendix 6080WB graphite plates has an altogether smaller soundstage relative to something like a Tung Sol 5998, Western Electric 421A, or even a Tung Sol 7802? Just curious is the is specific to my amp or a property of the tube in general.

Keep in mind that the chunky graphite plates require at least an hour to warm up .

Thanks, I've let them heat up well beyond that, but I will keep it in mind! On a more recent listen, I didn't find the differences as staggering as I once did, but still a smaller stage for me still.

Ok . For me I find the 421/5998 to be overall the better tube and the strength of the Bendix is in midrange timbre .
For soundstage the best in my amp are Russian or british tubes ie mullard 6080 or GEC if you can spare the pennies but the plain old 6N5S SVETLANA is a great low cost option

Thanks, that's really helpful. I have had a Bendix on hand for quite some time, but was surprised I did not like it much on its first pass, so it was set aside. I am going to give it another chance with its midrange timbre in mind. I am in the market for some GEC's, but they only come up so often and are hyperinflated given their scarcity. My amp takes a single 6AS7G output, so at least I won't have to worry about finding matched pairs

Nice set of tubes! Mind sharing your thoughts on WE 421a comparing to TS 7236? I'm rockin' TS 7236 / Chatham 6AS7G and Telefunken E188CC on my Eufonika H7 and I have WE 421a also coming in my way so would be nice to hear some impressions.

Oh, and enjoy your weekend with those lovely tuubz!

Just going off memory here, because I tucked the 421a away for them special occasions, like storing your best wine per se, is the better overall listening experience compared to the 7236. The 7236 seems to have a faster cleaner sound with tight bass. The 421a is lush and warm, with a huge sound presentation. With the right preamp tube..........Cha Bang!!

Anybody have info on National Electronics brand tubes? I saw a NE 5998 Made in USA. Hard to find any information about the brand. Maybe fake?

This is a question that Oskari could answer - he is one of our resident experts.

But I think it is safe to say that National Electronics was not a manufacturer. National was a reseller. So in this case, if it really is a 5998, National procured it from Chatham / Tung-Sol, put their name on it, and sold it in the market place.

There are tubes manufactured in Japan under the name National (NL) which became Panasonic later. And there also was a high quality US manufacturer National Union (NU).

I thought all 5998 tubes were made by Tung-Sol and just re-branded. That was what I read on the forums before. Can anyone here confirm this, so I know for myself?

I only mentioned other tube names connected to National - no connection at all to the 5998 tube. You can find the 5998 under several rebranded names such as Dumont, IBM etc, but they were all made by Tung Sol.

Yeah, I misunderstood that. Thanks for clearing that up.
