In Reply to: Are these even Siemens tubes? posted by Sigmund on June 9, 2025 at 19:35:05:
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 6922 tube date codes are A or A phi and Cca tube codes are G or G phi.
Can anyone tell me what I have? And what the dates codes mean?
Thank you.
