Not much is written about the E80CC tubes. There are a few brands out there - Philips, Tungsram, Siemens, Telefunken. But from the pics, I see only 2 different types structurally - Philips (with gold pins) and Tungsram (with silvery pins). Anyone with knowledge of the E80CC can shed some light on this?

Yeah, I was tempted to buy the Telefunken E80CC, but it looks very similar to the Tungsram, that's why I'm asking.
Philips, Amperex, some Siemens look similar (with gold pins)
Tungsram, Telefunken, some Siemens look similar (with silver pins)
Someone on ebay posted a pair of Valvo E80CC from Hamburg plant, pinched waist... for a very nice price of $395.

There is a some info on the different E80CC from what I have read the Tungsrams/Siemens with the nickel/steel pins are meant to be a touch more neautral and linear and the gold pin Philips/Valvo are said to be more coloured. I have only used the Tungsrams & Siemens E80cc but that seams to match what I am hearing.
Thanks. Will have another chatham 5998 Wednesday and thats me finished with the 5998 ................I'd liked to try the GEC tube next.I can't see anything wrong with the 5998 tubes in Hornet's pics. Is there something that I should be looking out for?
The next tube I really want to try is also the GEC A1834. Somehow, the prices on these are way too high. I wonder if the GEC 6080WA is a close enough compromise. Jamie speaks highly of the Mullard 6080, is that the same tube as the GEC6080?

I got a Chatham 2399 from vacuumtubes.net. Unfortunately it is extremely microphonic, I guess I will be sending it back. From reading online it seems this is common with the ones from vacuumtubes.net, I guess I should've done some more research before ordering. It really sucks that the 5998 is so expensive on eBay.
I got a standard RCA 6080 with my kit, and I picked up a Chatham 6080WA on eBay for cheap. So far I like the Chatham 6080WA better. The bass seems a little more controlled with it.
Right now I just have a stock Crack.

A microphonic tube in a headphone amp usually isn't an issue.
Yeah, that isn't particularly abnormal.

I have one just like it ;D
I took a stab at looking up the codes this is what I think they refer to
CV is the common valve name/type
The broad arrow is the UK Government issue mark,
I think the letter codes on the side under the arrow are date of manufacture July 1965
X denotes Director of Electronics Research and Development (DERAD) AIR approval.
Z denotes place of manufacture MO Valve Company, Hammersmith
