Hi, we only match power tubes. We do not match preamp tubes such as the 12AX7.
The numbers seem to match up, but will these work in my Orange BT500 Bass Terror Amp?

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.

When plugged in this tube has the following dimensions: 1.94" (49.2mm) x 0.87" (22mm). You will want to measure your existing tubes to insure a proper fit.

The S stand for spiral filament and refers to the internal construction. This will work in any situation where an ECC83/12AX7 is needed.

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.

J&J is my first choice in vacuum tubes for guitar and audio amps. Antique Electronics offers excellent range of products and has great customer service
Top shelf! Nothing beats quality and performance. If you want the best, buy the best you can..
Bought two of these, one was DOA. When they last longer than 0 days, that’s really nice, as they do the job well.
They’re inexpensive and have never let me down, I use them in every build.
