    Visual evidence Tung-Sol 5998 = Western Electric 421

    Interesting, JKDJedi and JTbbb. This makes sense. I think I'll try some other low testing tubes in an amp now. Maybe they'll sound just fine. 🤔

    Ok, thanks for your feedback! I think I'd like to try a OTL DIY with these someday.

    Ok, cool. Yes, I meant 5998. The Hickok 539C chart has a Gm test for this tube, but has a different test setup to only test emissions on the similar 7236 and 6250. Does Gm really matter much with the 5998 if emissions, shorts, and leakage tests are good? Is the Hickok 539C chart setup maybe not...

    Hi all, Can I ask a question here about testing 5988 tubes? Or, is there a thread specific to this topic? Thanks!
