12AX7 / ECC83S JJ VALVULA DE PREVIO
Larga durabilidad, alta ganancia y bajo ruido caracterizan a la ECC83S de JJ.
The JJ ECC83-S tube has several improvements in its construction from the old ECC83 version.
From our review of this tube: “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 JJ ECC83 / 12AX7 may be your solution.”
