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: Tamed the beast! - As many other reviewers have commented this is exactly what I wanted for my Behringer Tube Monster! I had a Groove Tube 12AX7 left over from a tube swap in my amp and replaced the stock tube in the monster with it. The JJ sounded good with my Telecaster, really good! However, I have a Stratocaster with Texas Specials and the hotter windings were just that too hot for the Tube Monster. There was zero smooth creamy overdrive! Just grind to super grind! Great! If that’s what your looking for. Enter the 12AU7. With the Strat there is at least a smooth transition from 0 to 1 1/2 then it starts getting gritty, in a good way! With the Tele.....Heaven!! Seriously, think Hotel California and Joe Walsh’s tone! Easily achieved! I do use a 2amp power supply for the Tube Monster because the 12AU7 although a lower output tube, does require more power than a 12AX7. ## Features - 12AU7 / ECC82 Preamp Vacuum Tube ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002M728O | | Additional Features | Lightweight | | Age Range Description | Adult | | Antenna Location | Audio Monitoring | | Audio Driver Type | Balanced Armature Driver | | Best Sellers Rank | #10,023 in Musical Instruments ( See Top 100 in Musical Instruments ) #10 in Guitar Amplifier Tubes | | Bluetooth Version | 4 | | Brand | british audio | | Brand Name | british audio | | Built-In Media | Cable | | Cable Features | Detachable | | Color | 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 out of 5 stars 262 Reviews | | Ear Placement | Over Ear | | Earpiece Shape | Round | | Enclosure Material | Faux Leather | | Form Factor | Circumauricular | | Frequency Range | 20 Hz - 20,000 Hz | | Headphone Folding Features | Circumauricular | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | Over Ear | | Impedance | 16 Ohms | | Is Autographed | No | | Manufacturer | JJ ElectronICs | | Model Name | T-12AU7-JJ | | Model Number | T-12AU7-JJ | | Noise Control | None | | Number of Items | 1 | | Specific Uses For Product | Music | | UPC | 844632022074 | | Unit Count | 1.0 Count | | Water Resistance Level | Not Water Resistant | | Wireless 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.

I had a Groove Tube 12AX7 left over from a tube swap in my amp and replaced the stock tube in the monster with it. The JJ sounded good with my Telecaster, really good!

The amp came with a 12AX7 installed. These low watt tube amps are all voiced to have gnarley overdrive when you spin the volume knob past 1. That's not my cup of tea, and also, I'd like to be able to run some pedals into the front end without getting mush from the tubes. As you may already know, a 12AU7 has the least amount of gain for a tube that's swappable with a 12AX7. Some people say that 12AU7s suck tone, but honestly, I've only ever noticed it when the volume knob is under 5 on the amp. That's not why you put a low gain tube in an amp! You put it in so you have more pre-amp tube headroom and you can crank it up and hear the power tube sizzle (or at least crunch a bit). You will need to bear in mind that switching pre-amp tubes almost always does change the sound of your amp – including tone, not just volume. That said, I find that nearly always, a lower gain tube like this 12AU7 will actually make the tone knobs more usable and more reactive. Anyway, on to the end of this review: I put in the 12AU7 into my 5-watter and it is just what I needed. It's a clean machine up to about 8 on the dial. Once you hit 10, you get that wonderful edge-of-break-up that everyone craves. Dig in and you hear the power tube work. Back off the strings and it cleans up. I can now put any pedal I want infront of this amp, and I can keep my tone pristine. That's what one of these babies can do for you. I do want to mention that more complex amps with several preamp tubes and power tubes do tend to be more finicky when you roll preamp tubes. That said, I say, "Go for it!" ## Frequently Bought Together - JJ ElectronICs 12AU7 / ECC82 Preamp Vacuum Tube - JJ Electronics Amplifier Tube (T-12AX7-S-JJ) - JJ Electronics Amplifier Tube (T-12AT7-JJ) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/3734228-jj-electronics-12au7-ecc82-preamp-vacuum-tube](https://www.desertcart.in/products/3734228-jj-electronics-12au7-ecc82-preamp-vacuum-tube) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-07*
