Appreciate that you posted the pictures - found that I have 5 of these tubes under the 6BZ7 designation. Gonna try them tomorrow - thanks.
Mordy, you want a RCA white label from the '50s. Not the orange label, not an alternate brand, but that tube specifically. The seller I link'd has those specific tubes. IME, most of the RCAs for sale are orange labels - not what you want.
I'm going to forget about 6BL7 for now. Thank you for the helpful discussion.
