1 answers So I have a couple of Presonus Studio Channel Mic Preamps and A DBX 376 and a one of those Eurotech dual ch. mic pres. I've heard that the Presonus Tube Ch.s can benefit from replacing the tubes. Are these good for my application?
1 answers Do these come in matched pairs?
1 answers I am replacing the tube that came with my Pangea headphone amp. it has 12ax7b written on it. will the 12ax7 work for the pangea hp-101?
1 answers I have a VOX VT20X how will it sound with a Tung Sol 12AX7?
1 answers What is the difference in gain and tone with the ecc83 and ecc803s (gold pin variation of this) and why isn't the gold pin listed as an ecc803s when it is on the box/label?
Asked by Anonymous on May 2nd, 2017.
Both of these Tung Sol 12AX7's are ECC803S. They are very close but the gold pin will have slightly less gain in the mids. The ECC83 is a mid gain tube and will have less gain than a 12AX7 (ECC803S).

1 answers Looking for breakup at low volume for practice with 1969 Bassman AB165. Would high gain preamp tubes help get there?
1 answers Hi everybody, my thought and question is as follows: Is the Tung Sol 12ax7 gold pin nearly same as the standard Tung Sol 12ax7?? Or is there a small difference in gain or in EQ power??
