Also found your post on audiogon about Watford and it looks like it's they have original m8080 for 15GBP. Tubeworld also carries pairs of m8080 for $80. I still don't know how much CJ charge for them?
Thanks again for your help
The 'M8080s' I find at Watford are Mullard CV4058s, also marked 6100, a known equivalent, and 7410, a number I know nothing about. My perhaps-commercially-labeled Mullard M8080s are also marked what appears to be exactly the same on the back. Here's a pic of some of my M8080s/CV4058s/6135s/6C4s.
From the left--2 RCA 6C4s, whose triodes look just like those in a 12AU7, which I understand is the 'same' tube but a twin-triode and having 9 pins; a Sylvania Gold Box GB-6135; 2 GE 5-star-labeled 6135s; and a pair of Mullard 8080s. I understand the 6135 to be a ruggedized version of the 6C4.

Good luck with your 6135s.
