A customer had recently sent us this email -
"Just an update on the "bad tube". I put another GT12AX7C that I purchased from you a while back into the amp and it jingles also but not a bad as the new one. This older tube has operated quietly in my THD Univalve . So I put the new "bad tube" into the Univalve and it sounds fine. The amp that causes the tubes to jingle is a Fender Pro Junior. I think that the GT12AX7C is not a good tube for the Pro Junior. The tubes sit less than an inch from the speaker. I tried JJs and Soveteks in the Pro Junior and they are quiet . So I guess I'll keep the GT12AX7C and use it in my other amps that are heads and not combos."
Before sending back a suspected "bad tube" , trying putting in other amps that you own. As he notes here, the GT12ax7-C works fine in his Univalve, but not in his Fender Pro Junior.
