More number deciphering
« : November 29, 2019, 11:08:39 AM »
Hello, So i have found the Tuner Sams 57-03-00 and the amp 175 Sams but it only covers up to FF and my mine is an AMP 175 GH.  Also there is another number 3-51-9 on the tuner and 2-52-9 on the amp is it correct the think it a 52nd week in 59 if so what is the 2 for?    I also now see the speaker code as 943 or 944 on all of them that seems to say its the 42nd or 43rd week in 59 correct ? I also found my console number listed on the ko 597 adapter kit which is the 3 tube MPX adapter which i now need to find! so asking here first if anyone has one.

I would not be too concerned with the suffix on the model number.  Magnavox did that commonly.  Probably slight differences in the setup pertaining to how the amp was installed.  The schematic you have should be close enough.  If you not differences in the schematic and the setup you have, make notes of the differences.  Then either you can investigate and troubleshoot according to the setup you have, or ask on here and someone can talk you thru it.


The "2" and "3" may refer to the shift the amp was inspected, or may refer to the inspector who passed it.  Which is which, exactly, may be lost to history.

Hello, looking for speakers on eBay i now see the 232 is magnavox. Their code so to speak  then the one digit year and then the two digit week  say 232 450 would be 1954 and in the 50th week. but how do you know the difference between a 1954 speaker and a 1964?

You might not be able to ascertain the year, exactly, by the speaker date code.  You might have to refer to tube date codes and the general build date of the equipment it was in.  If you are buying just the speaker with no other codes to compare, you might not be able to tell what year it was between 1954 and 1964.  If you checked the EIA code for the manufacturer and they weren't building speakers in 1954, but were in 1964 that might be a clue.
