post #1336 of 3800
I think you mean 6528. The 6520 is identical to the 6AS7/6080.

Oops, right, early morning misreading error on my part.

The 6520 sounds great in the 339 though, but I don't use them that much at all as I only have one pair

Hi,

  anybody here have a Tung-sol 6080WB graphite plates?Can you please post a picture so i can do a comparison to the tube that i'am about to purchase and also if you can give me an idea how much they go for same for Chatham 6ASG.THANK YOU! 

post #1340 of 3800

I have found a 6080 tube that has me puzzled, I'm not sure where it came from or even what the brand/maker its from.

 

I'm hoping someone might recognise the small section of printed logo which still remains. It looks very familiar and its annoying that I'm unable to recall it.

 

TIA

While I don't have any graphite-plate 6080WB's, I can suggest this website for some good pictures:

While I can't see much detail from your pic, the plates, and top and bottom mica resemble the Mullard (Also labelled as Telefunken, Valvo and GEC) CV2984 6080WA shown on the bottlehead site I mentioned above:

That is a great topic on those tubes there is but it is not complete. We completed the 6080wb list here on Headfi (if it ever will be complete I don't know)

That's basically German military. BWB = Bundesamt für Wehrtechnik und Beschaffung = Federal Office of Defense Technology and Procurement.

That's neat thanks and make sense as looking at the image it does look like half a eagle.

That's true. This is particularly confusing:

II.d) $50 (NIB) Mullard (Also labelled as Telefunken, Valvo and GEC) CV2984 6080WA

 

 

The valve shown is a GEC (made by MOV). Mullard made their own version, and I think that Telefunken also made some.

post #1348 of 3800

It is useful to know that the valve pictured on the bottlehead site was manufactured by GEC, and that Mullard made a different version. I have seen a number of Mullard-branded 6080's and wondered why they were different....

 

For example:

Great that helped and your spot on thank you.

 

its a MOV made Valvo / GEC. I had a Valvo 6080 so dug it out and its identical, plates getters base all exactly the same the Valvo also has the MOV Z factory marking as well as the BWB Eagle mark.

 

 

 

 

While on the 6080 Mullard subject I seem to have three version. This the oldest it did once have a faint chalky shield logo now long since gone from hot tube removal with a my special sock and my other half thinking it needed a go over with some glass window cleaner. I also have two version of the more modern one but one is a flasher on start the other is not.

 

This is the older one

Holy crap the guy is asking $75( one tube) + shipping  for the Tung-Sol 6080WB graphit plate. WOW! Is this tube really worth that much?Does it sound a lot better than those other 6080's?
