    EAR834 tube rolling

    After trying some ways with some tubes and I found the 6211 (12au7) gold pin from Telefunken was the best (may be) with my system. I replaced the V3 and then V1, I'd love V1 rolling. Sound stage was opened and larger, the 3D effect was clearly, more details and balanced. I'm waiting for the Siemens 12au7 and 12ax7 long plate and try again to find the best. Thank you for your advice! tungh P/s: The Telefunken 6211s are too expensive now, you can find them on eBay.

    I found a 6211 tube on the local store, I searched for the information and some results said that was the 12au7, but some said was the 12at7. Did you have any experiences about this tube? Please give me an advice! Thanks so much! tungh

    Dear Paul, Thank you for your information! So you meant the 5963 (12au7) should be in V3, and 5751 (12ax7) in V1, is it right? And how about the V2? I agreed with you the gain is overloading with some pre. When I use my Ortofon MC30-W and the gain is out of control. tungh

    EAR834 tube rolling

    Hi rabski, I am very sorry to ask again, it finished a long time ago. I also bought a new Ear 834P Deluxe, I search from a lot of forums to find the way to change its default tubes. I found out that I should change the V1 by 12au7 and keep 12ax7 for V2, V3. Now I am using 3 of Telefunken 12ax7s smooth plate (named The Fisher) and I can feel the sound is better than the original tubes. But I think the Ear could be better and better, so at the end please tell me some advices for my phono. Thank you so much! tungh P/s: I am using Micro Seiki BL91, Micro MA505 mk3 tonearm, Ortofon MC30 Super Mk2 and the Hashimoto HM7 step-up. My amp is Gryphon Callisto 2100 and the speaker is Marten Duke mk1.
