1000+ Head-Fier
Yes, I’ve had success with NOS Mullard (50’s and 60’s), Svetlana winged-C are excellent newer tubes, and 60s Chatham 6as7g (I’ve got several of those as well) are very good. I couldn’t comment on pricing, as I bought my sets years ago.Good pairs of those two may now cost over $500. Are there substitutes getting close to the performance but cost under $250? I am looking into Tungsol/chatham 6AS7G, 7236, Svetlana 6H13C, maybe Mullard 6080 etc. Do they work well with WA22? I had these with Euforia before. I liked Chatham 6AS7G, but not as good as 5998/421a when I had them.
I am also looking at GEC A2293 that CAJames recommended. The challenge part is to find a matched quad.
