"JJ 12AX7/ECC83 These are near exact copies of exotic and rare Telefunken ECC803s. (not the flat-plate ECC83..the really rare frame-grid style which cost $100's of dollars if you can find any). Get close to real Telefunken sound at a fraction of NOS prices!"

"This tube sports a different plate design than found in most 12AX7's. When you look at them you can't help but think that they must be rugged and good for the musician on the road. The compact plate structure does nothing to dampen their sound or dynamic response. I find them to be well balanced. While not as harmonically rich as others I tested, they do provide high gain without the usual noise and microphonic problems you would expect. This is great sound for your dollar. If you're using a combo amp and find the Philips a little rich sounding, the Tesla / JJ ECC83 may be your solution."

"JJ ECC83: Middy when clean, but also chimey. Very full harmonic content. Excellent! When distorted, very full and still retained good harmonic content."

"This is the latest 12AX7 offering from JJ. The original JJ ECC83 was a great tube and came very, very close to my all time favorite Telefunken 12AX7’s. In fact it was very hard to tell them apart in some amps. The new "S" tube is even better! A tighter low end, a more natural and even more defined mid and the high end has more detail and is even sweeter than the original. The best part is that you can buy a new tube that sounds this good for one tenth the price of an NOS Telefunken."
