Yeah, I wasnt overly excited about the NOS TungSol the same, however..the NEW (russian made) Tung-Sol.. I like, I also have a Westinghouse and dig the crazy width it has. And yes, the GE I just got is staying in (for now, swapping power tubes for best match ). And thanks for the heads up on the Silvertone. What numbers does that have? Usually a give away on who made it for them.
edit: found it! it's a Sylvania. https://www.worthpoint.com/worthopedia/sylvania-silvertone-6sn7-tube-vintage-111579344
Cool, good to know.
Like I said, the combo of the GE GTB and the GE JAN is pretty stellar. May want to give the GE Jan a shot. I got mine from Parts Express ebay store front for $18.69 shipped .
