I have a pair of what I believe are Siemens E188cc tubes branded Cca. The date codes don't look like Siemens codes I've seen; there are no phis on either tube.

I know that their 6922 tubes have date codes beginning with A and their Cca tube codes begin with G.

Can anyone tell me what I have? And what the dates codes mean?

Thank you

Thanks, Joe. This is marginally helpful. Nothing about dates, though. - Sigmund 06:39:10 06/10/25 (5)
