That's a shame and a bit of a surprise, could have swore they have had matched quads listed in the past as well as the matched pairs they have listed at the moment.
For 6AS7G tube rollers here .....

A nice pair of 6080 arrived here the other day:
While "Made in Holland" is written on the boxes and tubes, the Philips production code reveals that these were in fact manufactured in Mullard's Mitcham factory. The code suggests that these were manufactured in October of 1957 or 1967. However, the change code of "0", the metal shielding above the top mica and the text and graphics on the boxes leads me to believe that 1957 is more likely the case.

I gave $75 for the pair with free shipping... As these are my first old Mullard 6080s I can't say if this is "cheap", but with free shipping, I didn't hesitate.

Nice.
Langrex UK has shipped me samples of their Mullard 6080's. As soon as I receive I will give them a go and post my impressions.

There are at least two versions of the Mullard 6080. The older shorter bottle on the left with sheetmetal shielding above the top mica is 1950's vintage, and the taller tube on the right is later. I haven't had a chance to compare these, so I can't comment on how they might differ sound-wise....

The short bottle Mullard with the radiator on the second spacer is often branded as Philips ECC230. I think they were made in the 50s and were replaced by the tall bottle design some time after.
It's a great tube by the way. I prefer it over GEC 6AS7G and Tung Sol 5998 due to its full/rich tone body. They lack some detail but its tone compensates for that. It's just a shame most of my Mullard 6080s became noisy at some point. Three out of five.

These are the ones I was looking at. I thought I would give them a go. I have tried the Tung-Sol / Bendix 6080 and Tung-Sol 7236 (both very expensive tubes). Neither has impressed.
This Mullard looks quite different than Gibosi's between the top 2 spacers and got me thinking where I had seen this before. I pulled out my 80's Thompson 6080WA and they could be twins. Did the french factory use Mullard tooling? This tube is what I mean http://www.ebay.com/itm/Thomson-CFS-NOS-NIB-6080WA-black-plates-tube-France-Test-NOS-/171387179627?pt=LH_DefaultDomain_0&hash=item27e778d26b

The top two micas in the Mullard are round with spikes, whereas the Thompson has smooth round micas with no spikes and rectangular mica spacers making contact with the glass on each side of the top mica. Further, the Thompson has a number of U-shaped heat-radiators on top of the second mica while the Mullard does not. So in terms of construction, these are quite different.
That said, the plates in every 6080 and 6AS7 all look so similar it makes me wonder if they were all sourced from the same company... But this is just wild speculation on my part.
