Genalex - Gold Lion ECC82 / B749 | Better then or at least as good as the telefunken NOS

by -

Was strictly nos Telefunken when choosing the 12AU7...not any more. I bought 6 of these GL-ECC82, they are unbelievable.

Genalex - Gold Lion ECC82 / B749 | A giant step in the right direction


A small step forward in the tube domain is a giant step. So with that said, I was wanting to add some spice to a pair of Klark Teknik eqs to get them a little closer to my pultec EQP-1A. The stock tubes in the Klark were actually quite good (I was surprised), but the Gold Lions GL-ECC82 added extended lows that were a bit tighter, a more balanced mid section, and a little more air on top. The result was bigger, warmer, clearer sound...not by a lot, but a little goes a long way. Glad there is an alternative to the ridiculously priced NOS tubes.



The Yaqin MC13S amplifier is a clean enough Class A amp. The stock tubes are pretty Average. Dropped a balanced pair of these into the push-pull stage (with a pair of ECC83's). Never mind burning in - the whole amp just opened up. Keepers.



كاملاً متفاوت،سكوت،تايمينگ فوق العاده،آنالوگ خالص،صداى گرام

Completely different, quiet, wonderful timing, pure analog sound.



This tube blows away all the Nos I have, RCA,Westinghouse and Valvo. Better soundstage than any of them!
