Jensen BL-250 TriPlex, pics!

[Jenkster]

I just aquired a pair of these from a friend. One cabinet is pretty much complete save for the replacement JVC tweeter. The other has the horn and driver, crappy replacement woofer and the same JVC tweeter. Anyone know approx. when these were made and if the horn, P15LL woofer and crossovers are original to the cabinet? Also, any idea which tweeter was used? I may try to use just one as a mono cabinet. I have an old Fisher mono tube integrated somewhere around here. Can't find anything on the internet about them.

Thanks in advance fo the help!

Best single source of Jensen info:

Second best source: Peruse 1950s/1960s Radio Shack catalogs at www.radioshackcatalogs.com

Third best (but slowest) source: I can look at old Lafayette and Allied catalogs and see if I can find anything

The woofer and compression driver/horn (and XOs) look to be original to me, but I dunno.

Thanks so much MrH! Looking at those old catalogs it appears they are from 1956 or so. Just a touch older than I am.

The system includes P15LL low frec., RP-301 and RP-302 mid and high frechency units. 15 ohms impedance .Very efficient. The crossovers seems to be the originals. I have one of these systems that belonged to my father and I think I is from 1958. The high frec. unit has a large alnico magnet and seems to be a compresion driver, "Harshy"
sound (hard phenolic diafragm). Will look if can find the brochures and if you want can send you pics. Once I saw one P15LL for US$ 600 on ebay !!!

Pictures of the brochures would be great, thanks! It appears they made some different versions of that woofer. I have seen some that were in Leslie cabinets that appear to have a different magnet structure. This one says "wide range" which I assume means it's designed to cover a larger frequency range than the standard 15 incher?

Thanks for the info!
