Hi, I haven't been able to find anywhere in the web a straight answer about the actual technical difference between regular and gold versions of these great tubes. I don't mean the difference on how they compare soundwise, but on the technical paper: Is it just the gold coated pins and the rest is the same? are gold pins maybe factory selected under another criterion before gold coating? etc... Thank you very much! Your tube comparison chart is awesome!

The pins are gold and this helps to prevent corrosion and buildup on the tubes pins. Other than the pins, they are the same tube as compared to the regular pin version.

The S stand for spiral filament and refers to the internal construction. This will work in any situation where an ECC83/12AX7 is needed.
I bought my first tube amp, will these tubes help my vht special 6 sound less boxey/muddy so i can get more tone?
Asked by Anonymous on October 6th, 2017.
Tube characteristics can be different from brand to brand, and because the tone of tubes can be highly subjective, we can not verify if these tubes will get you your desired tone. You can visit the "Tech Corner" of our website for a 12AX7 comparison of current made tubes. This has a wealth of information to help you make a decision.
