>:The stamp on MINE (a Jensen alnico 5 concert series "blue cap") says:
22087

>:Question #1: Does this mean the speaker was produced in week 7 of
'58? Does
>:it HAVE to be a six-digit number?
>:
>:
>:Also, the "letter code" on the tube chart says (according again to
the Tube

don't
>:remember the exact letters.... "HJ" I think!) Problem is, according
to the
>:book, Fender only produced the tweed Tremolux through 1959.

Go with the amp code.  The speaker may not be original.
