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. ## 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.be/products/3734228-jj-electronics-12au7-ecc82-preamp-vacuum-tube](https://www.desertcart.be/products/3734228-jj-electronics-12au7-ecc82-preamp-vacuum-tube) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-14*
