Members slej Posted December 7, 2006 Members Share Posted December 7, 2006 These are a few Silvertone 12AX7A tubes and also an RCA and a Sylvania (yellow lettering). They are "pulls." They tested better than contemporary new tubes; they are clear appearing and the labeling is legible. I think the Silvertone tubes are the same as RCA gray plates and were made for Sears. I don't have pictures but feel free to inquire. ldm5@hotmail.com Link to comment Share on other sites More sharing options...
