    I'd suggest shooting them with a pellet gun.
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

    Dukane's were commercial paging amplifiers / background amps in retail establishments, warehouses, etc as far as I know. It probably looks like a tube amp without the tubes. I think some might have made their way into generic solid state console radios in the 60's and 70's.

    Check your lips at the door woman. Shake your hips like battleships. Yeah, all the white girls trip when I sing at Sunday service.

    you the man russ! i got these from the catapillar plant in mossville illinois when the entire phone/paging system was upgraded. my father in law was a wazoo phone and electrical guy. i have about 10 of these and have heard they are very strong as a high frequency or tweeter bi amp. may make a run with them on my test system when i have the tunes to motivate me lol. do you know if the input tramsformers can be replaced with respect to tubes in place of the 2n 3055s? if nothing else the ac transformers will supply a small town as there are two of them per.

    I was wondering if you have any idea how to tap a dukane 1a753 for 25v. I believe terminals 5 and 6 are jumped, then 4&3, output to 1&2?

    I have a pair that I put in my garage. They are paging speakers but do a decent job for listening in the garage.

    Even for a garage, they are awful.

    HOWEVER, the garage is the best place to stage loudspeakers you find on the fly. I had a 19xx Telefunken tube console station that I rocked in my carport for years, and I got it FREE. I loved it and eventually parted it out to some folks in Asia. It was a beautiful Teak full length setup and I miss her so I guess there is some merit in it after all...just don't bring it INTO the house. That's for Audio Karma folks.
