Offered for your consideration is a vintage Jensen mid or high frequency adjustment knob removed from my LS-4b speakers, USA-made in 1981. This is the same knob style used on the LS-3b, LS-5b, LS-6b, and the earlier LS-3, LS-4, LS-5, and LS-6. The knob may also be correct for other period Jensen speakers, but you’ll have to make that determination by studying the photos. So, please have a look at the photos and measurements I’ve taken to decide if this attenuator knob is correct for your speaker. *Although the listing is written largely in singular to avoid any confusion, four (4) identical Jensen attenuator knobs are available at time of this writing. Please choose if you’d like to buy one or more in the quantity field at the top of the listing. The shipping cost will stay the same regardless of how many you purchase. This Jensen mid or high frequency adjustment knob is in clean, excellent condition. It’s made of hard plastic with striated grip surface and measures ?” in diameter at bottom x ¾” tall. There may be some very small imperfections, mainly at the bottom edge if any, but that’s all. Plus, the recessed lobe has knurling to hold your speaker’s attenuator shaft securely. As pictured and described, this useful Jensen attenuator knob is offered at a reasonable price.

Offered for your consideration is a vintage Olson model S-713 12 inch full-range guitar speaker, USA-manufactured by Jensen c.1968. Olson sourced all of their speaker drivers from outside suppliers and this speaker came from Chicagos Jensen. A helpful eBayer informed me that this Jensen driver uses the same cone as their venerable C12N.Please have a look at my large photos and read the remaining description to decide if this capable Jensen guitar speaker should be yours. This Jensen for Olson guitar speaker is in clean, very good condition. The ribbed, deep-set paper cone has a thin crack, right next to the factory seam, which I neatly secured from the back side with surround glue. There is also a very small fissure on the integral hard paper suspension ring which I corrected the same way. The cone is otherwise unharmed and the vented voice coil dustcap is perfect. Plus, the attractive, “futuristic” cast basket is in great shape with no dings or scratches. And, the +/- input terminals are sturdy, screw-tighten binding posts which add a very nice touch. It’s a well-preserved driver, overall. Most importantly, it’s been fully tested and sounds very strong and clear with clear, detailed lower midrange extending deep into treble, and ample bass. Plus, I tested its DC resistance at 6.9?, consistent with a nominal 8 ohm driver rating. Lastly, the mount flange measures 12?” diameter, it stands 5¾” tall, and the mounting holes are spaced 8¼” adjacent / 11?” diagonal apart, c-t-c.So, as pictured and described, this Jensen for Olson 12” full-range guitar speaker is offered at a competitive price.
