There is an easy way to determine the date of your vintage Jensen speaker. On the edge of the speaker where the mounting holes are there will be a six digit number. The first three numbers will be 220 which denotes the manufacturer as Jensen. The next number is the year of manufacture and the last two numbers will be the week of manufacture. So if the number on your speaker is 220947 it will read as follows; 220 is the Jensen manufacture code, 9 will be the year and 47 is the 47th week of the year. The problem is the number 9 does not determine which decade (i.e. 1959, 1969). To determine the decade the speaker was made try to base it on what year the amp was made that it is mounted in. If it is a raw speaker then you have to make an educated guess.

Testimonials:
David Nicholas - The 20watt amp is sounding fantastic! Delivered the goods at the gig and I'm finding cool tones all over the place with it. Love the cab w Emenince Tonkerlites too- perfect for my sounds! Makes the 12 string sound like a grand piano!
Peter Lacis - I had an audition for something recently that was all about Led Zeppelin I -- my custom Pennalizer BLEW THE MINDS of the guys I was playing with. They couldn't believe the sounds coming out of that amp. That album was never in my mind when I came up with the idea....so that's yet another testament to the amazing work that you do.
Scott Goldberg - I am very satisfied with the set-up, and the fast turn around. With the "lower" action it feels easier to play. I will definitely spread the word.
