Siemans Halske codes

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

I have a 17 mm long plate ecc83 Rogers (Canada) labled with the Munich factory code between the pins of #Y mCP.

Can anyone tell me the meaning of the code? Dave

Not sure about details, but it's certainly 1950's production. The mCP part is the type code, and this kind of code is found on the earliest Philips versions.

"#Y mCP" specifies manufacture in Munich, July 1955.
