More food for thought for you guys. If extremely MASSIVE soundstage, and a smooth warm syrupy sound is an absolute must. You can give these a shot. My second favorite tube in my collection. Adapters: You'll need 2 of course. https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/191554107223 6c8g tubes: Tung-sol black glass/ round plates (which I'm currently selling a spare pair from this seller). https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/202012976996 Yes, the Soundstage is huge.
