I'm not a big fan of the Mullard ECC35, so I'm not willing to spend the money asked for the ECC32. Don't get me wrong, the ECC35 is a nice tube, but I believe there are better and cheaper options for the 6SL7 slot on the LM508. Of course regarding my sepakers, taste, room, system and valves synergy, etc etc. Nevertheless, as a lot of people "rave" on Mullard tubes, the CV6 and EL32 options are much reasonable in price to try. How would you describe their sound? Would you recomend them considering the best ones you have tried on the 6SN7 slots? I know this is personal taste and dependant on many variables, but it would help us to know your opinion. Also, if you think theyt are worth to try, we would appreciate if you could send us the link for the adapters as the ones on the pictures seem leaned 45 degrees to fit on the Lm508.
