Nice tubes!

 

I believe you intend to use these 5998's in your Crack? I seem to recall reading somewhere that in order to get the best sound out of these in a Crack, it is necessary to change the cathode resistance. You might want to check into this....

I bought NOS 7236 just last week for $23/each for matched pairs. Excellent deal!

I find it interesting that the most common tubes are often the least appreciated

My amp had a winged C when it arrived and I liked the sound the Svetlana tube gave but curiosity sent me hunting for something more exotic

After a little while hunting I sourced a 5998 for a reasonable price

My amp was transformed it was like dropping a v8 into a four cylinder car , more everything

Recently my much loved 5998 developed a slight ring in one channel

So while hunting once again I decided to drop in a RCA USN CRC 6080 WA 1957

I purchased this tube because I needed a backup and it was $6 for a tested NOS NIB

Any way this little tube is great , while it lacks the power of the 5998 it is so clear and totally noise free I think It deserves a little of the spotlight

Continuing the Bendix Graphite Plate 6080 conversation from page 91. Just got mine today & they have Rectangular plates / columns in the shape of a cross (+) & with a curve. Is this type 4 out of the 6 types listed by Ultrainfernorosgr63 ?

Also when you say Steel / Copper rods do you mean the rods on the right & left of the plates or are they the rods in between the 2 plates (with a grid in pic 4)

On the solid column graphite 6080WB I have the outer support rods are all SS afaik, the grid support columns appear to be copper (judging by colour).  Mine look a lot like yours, below you find pics of one TungSol labeled 6080WB next to a 'Hytron' labeled one.  The separation discs appear to be different in colour but otherwise construction looks identical to me.  The one with the white discs (Tung Sol label) looks a lot like what you have in your picture.  I honestly wonder how many individual manufacturers of these there were and wether or not they used the same supplies in construction.  But judge for yourselves and 'find the differences':

The Bendix I have has a + (Cross) shaped column, whereas the Tung Sol & Hytron posted above have hexagonal circular columns (Just like the Chatham 6080 Graphite Plates I have) . The one on the left is the Bendix & the one on the right is Chatham :

In my limited experience, I have never seen a Chatham/Tung-Sol 6AS7G with steel grid posts. All that I have seen have had copper posts. Has anyone seen one of these with steel posts?

Rounded cross....interesting version I've not seen before.

       Same here  copper posts.

sure, they're around

The rounded cross Bendix 6080WB graphite is very interesting, never saw one before, I know the straight cross solid version exists.  As for my hexagonal column TungSol and Hytron tubes pictured above, I'm pretty sure they were made by the same manufacturer but just sport a different label.  Construction is identical and on top of the valve is a printed octagonal label indicating '6080 WB' with beneath the octagon 'U.S.A.', see pic below, right one is the TS, left Hytron.

....and for those wishing to take a walk on the wild side:  here's the 6528 tube plugged into my DV 337, this fits an 6AS7/6080 socket but is a high gain tube (mu of 9) and with a heater drawing 5A (double of a 6080) so make sure your amplifier power supply can take it, if it breaks you get to keep the pieces.  They're still burning in at the moment, a bit microphonic and 'pinging' during warmup (first 5-10 minutes).  Sound promising though.

Wow...the 337 can supply 10A of heater?
