Best replacement tubes for my CJ PV14L have M8080


I know nothing about tubes per se. Am looking for the best replacement tubes for my CJ PV14L - the unit came with Mullard M8080. on the back of the tube it says, the following which means nothing to me:
6100
7410
CV4058
KB/QDD
I got a 6C4s sent to me which didnt work - the company sent the WA version (which I didnt order) and it did a few weird things.
If I can improve the sound i would be very happy.
Thanks.

The 8080 is not a very common tube. I don't know if you can find a sub for it. I would check with tube sellers Tubemonger or Brent Jessee, both of whom can be found on the web easily. They both know tubes and are honest sellers.
