EL34 tubes Vrs. 6L6 tubes

Call the manufacturer and ask how many volts are going to the plates of the 6L6. If it is not more then 320v, try some NOS RCA,Tungsol or Ken-Rad 6L6G. These have a very different sound then the EL34's and once you hear the difference you might never go back to the EL34's. They are very musical and give wonderful body to the music. Please check with Esoteric first. Leave the 6L6GB and 6L6GC alone. Try the 6L6G or 6L6GA. They are a bigger tube being the shoulder variety so make sure they will fit in your amp before buying a pair or quad.
Good luck,

I thank you for the input. I am currently searching for nos 6l6 tubes. I will advise you of the results.

*** I would like to mention that I have run tube amplifiers since 1975. I Started with Audio Research D-51, went to a D-75, D-76, experimented with Dynaco stereo 70's, back to ARC D-76 and D-51. I loved the 76 but wound up selling the D-76 after the old stock tubes wore out. ***I replaced the worn tubes with Russian tubes and the sound was hard and metallic, similar to a solid state amp. The amplifier never sounded musical with Russian tubes. I replaced the Russian tubes with Tesla KT-88's and it sounded pretty good. I guess the old tube designs contain some hidden secrets, or it could be in what types of steel were used in the making. Whatever it is, it just hasen't been passed on to the new tube manufacturers. I will keep you posted.

I found the 6L6's to be only slightly better in the mids. And when it came to bass it was non-existent compared to the el34. Try Svetlana el34's, in my amps they smoked the Tesla's

Can somebody tell me were I can find some EAR 864 for a low price (I'm from France) Many thanks. e-mail me please at : claro@univ-lille3.fr

The 6L6 will produce deeper tighter bass.
