I bought a pair of Siemens E83CC many years back (I actually forget about it ). I can see the triple-mica. The words on one tube is faded but the other one can be read. How do I interpret the code 34300? Which year was this made and where?
Hi, after posting this, I learn from another forum that I need to read the acid etched codes for the info. Unfortunate the acid etched code on one tube is so faded and not readable (I didn't notice it at first) and I couldn't see it at all on the other tube.
