Review: Is an upgrade to no-name tubes - I bought this pre-amp tube as an experiment for my 5 watt Vox amp which had very little headroom before going into distortion. I wanted a cleaner native tone and to get FX such as distortion with pedals. Upon some questioning in a guitar amp group I learned changing out the 12ax7 would have dramatic effect on that which it did. Unfortunately I think I went a bit too extreme as this tube literally requires my amp to be almost at full volume just for bedroom jamming which is all I do these days after retiring from the music biz. But with that I will say the amp sounds better overall with this tube replacing the no-name 12ax7 it originally came with, and not just the headroom but it also seemed to help with the "fizzy" tone the amp had. Although I going to do some more experimenting with different tubes this tube will still come in handy as I have some other single pre-amp tube gear I believe would benefit from the restriction this tube creates so it's a win win. Review: Marshall DSL1Tube upgrade - I bought this 12au7 a 12AT7 and two new 12AX7's to replace the stock tubes on my Marshall DSL1H. Going purely off of reviews i wanted to try to make the gain more usable and and reduce the compression a bit. 1- the 12AT7 turned out to be to much of a power loss i dont recommend. 2- I put the stock 12AU7 back in with the mullard 12AX7's and it still had decent compression and some of the fizzy gain the stock marshall tubes produce. 3- I put in the mullard 12au7 wich removed the compression almost complestely and reduced the gain by about 20% making it more usable across the range. That said i think i liked the marshall 12au7 along with the mullard 12ax7 combination the best it has a nice compression cranked and a nice distortion to my ear it is a very nice inbetween compromise. I highly recommend trying the stock 12au7 for the power amp and the mullard 12ax7s in the pre amp for a nice balanced tone that still rips when you want. Hope this helps. ## Features - Great sounding tube - Low noise and mircophonics ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #59,725 in Musical Instruments ( See Top 100 in Musical Instruments ) #245 in Guitar Amplifier Tubes | | Customer Reviews | 4.5 out of 5 stars 122 Reviews | ## Images ![12AU7 Preamp Vacuum Tube, Single - Image 1](https://m.media-amazon.com/images/I/71O0BKB32tL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Is an upgrade to no-name tubes *by G***L on August 2, 2026* I bought this pre-amp tube as an experiment for my 5 watt Vox amp which had very little headroom before going into distortion.

Would by again. *by J***O on May 11, 2025* The Mullard tubes were a definite step up from the stock core tubes on the Gremlin amp. And I liked the stock core tubes. But the Mullards are step up in every way. They have that tube warmth and very full deep base. The sound stage is better as well. The highs are good and dynamic when need be. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/39184640-12au7-preamp-vacuum-tube-single](https://www.desertcart.fi/products/39184640-12au7-preamp-vacuum-tube-single) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-10-03*
