They are reliable, well made, reasonably priced, and they sound very good imho. This preamp tube is a good choice if your amplifier has more gain than you need and you are looking to take it down a notch from what a 12AX7 is giving you. You can also use this tube to modestly increase clean headroom on some low watt amps. I used it to bring down the gain on an overdrive pedal that used a 12ax7. I bought this tube through desertcart with the vendor Musician's Friend. When the tube did not arrive, they sent a replacement via 2nd day mail. The original eventually made it's way to me and they told me to keep it- Thanks, Musician's Friend :) Review: Great sounding tube - I bought this 12au7 to replace the blown 12ax7 in my Orange Micro Terror and the difference in how my amp sounds now is exactly what I was looking for. Basically, this tube allows me to turn the gain up without getting fizzy, almost-useless distortion. I used to have to keep the distortion down low, especially if I wanted to use a dirt or distortion pedal. It almost always sounded bad with the ax7 but now with the au I get an even smoother distortion (it sounds even better now) towards the end of the knob's range and I get nice usable clean-ish pedal-friendly tones. ## Features - 12AU7 / ECC82 Preamp Vacuum Tube ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002M728O | | Age Range (Description) | Adult | | Audio Driver Type | Balanced Armature Driver | | Best Sellers Rank | #8,687 in Musical Instruments ( See Top 100 in Musical Instruments ) #8 in Guitar Amplifier Tubes | | Bluetooth Version | 4 | | Cable Feature | Detachable | | Color Name | Black | | Compatible Devices | Desktops, laptops, mobile phones, tablets, music production equipment, smart speakers, TVs, car audio systems, phones, game consoles, motorcycles | | Connectivity Technology | Wired | | Control Method | Remote | | Control Type | Remote Control | | Customer Package Type | FFP | | Customer Reviews | 4.7 4.7 out of 5 stars (258) | | Date First Available | June 27, 2007 | | Earpiece Shape | Round | | Hardware Interface | 3.5mm Audio | | Headphones Jack | 3.5 mm Jack | | Included Components | Cable | | Input Device Interface | Audio jack | | Is Discontinued By Manufacturer | No | | Item Weight | 0.352 ounces | | Item model number | T-12AU7-JJ | | Manufacturer | JJ ElectronICs | | Material | Faux Leather | | Material Type | Faux Leather | | Model Name | T-12AU7-JJ | | Noise Control | None | | Number of Items | 1 | | Product Dimensions | 2.5 x 1 x 0.9 inches | | Recommended Uses For Product | Audio Monitoring | | Special Feature | Lightweight | | Specific Uses For Product | Music | | Supports Bluetooth Technology | No | | UPC | 844632022074 | | Units | 1.0 Count | | Water Resistance Level | Not Water Resistant | | Wireless Communication Technology | Bluetooth | ## Product Details - **Brand:** JJ ElectronICs - **Color:** Black - **Ear Placement:** Over Ear - **Form Factor:** Circumauricular - **Impedance:** 16 Ohms ## Images ![JJ Electronics 12AU7 / ECC82 Preamp Vacuum Tube - Image 1](https://m.media-amazon.com/images/I/6192XRwcpRL.jpg) ## Questions & Answers **Q: 9 pin?** A: Yes, this tube has 9 pins. **Q: Can these tubes be used in a vintage Vibro Champ?** A: Read through a few articles about your vintage Vibro Champ, and it looks like the consensus is that this tube would work better for the V1 position. V2 would be a 12AX7, V3 6V6, and V4 5Y3GT. It is my understanding the 12AU7 has less gain. You could try a few different tubes in the pre gain to see what you think. **Q: I assume 12 AU 7 is two tubes in one obviously maintains stereo sepeartion Common cathode which is grounded normally anyway ?** A: To be precise, the 12AU7 is two independent triodes in a single tube. Like any other electronic component, these can be used in all sorts of applications, limited only by the circuit designers imagination and ingenuity. They can by used in audio and RF circuits... These could be used in a stereo design, but they are not limited to that application. The cathodes are not common between each section, and depending on the circuit design may operate at some potential other than ground. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great tubes *by C***E on December 6, 2012* JJ tubes are my preferred tube manufacturer these days.
