Ah Yes!! I overlooked the 3 separate dial knobs! I have a "unknown" brand 3-dialer battery trf set here in the old "coffin box", think its a old "kit" radio( unmarked brand) that I will be restoring someday. It has the old small square-copper rods wiring assy, carefully soldered together, and if I remember correctly, it uses all O1A tubes in its old bakelight 4-pin (twist-style) tube sockets using short tube pins? If you need any assistance in finding good spare orig AK parts for your vintage AK setup, check with Ray Thompson! He may even have a original driver for the Horn Spkr, but then again, Im not sure. You bet, tuning in 3-dialer sets arent that hard, but I only had one other set here in the past of that "vintage" before. It was a Freed Eisemann vintage 3-dialer. I replaced the old grid-leaks, built a DC power-supply, and got it working with its orig tubes still intact. All the tube-filaments were still good!Some of the early AKs also used a couple #26 tubes also if I remember correctly? The orig audio-trans were still good in that Freed Eisemann set also. The old linear taper vol-control was in bad shape, but worked again after careful cleaning the rheostat coil, and relubing with WD-40. That radio had a crystal-type headphone jack output, if I remember correctly, that could be also used to horn spkr also. I borrowed some old vintage headphones from a local ham-operator to use to hear it to make sure it was working as I dont own any early-type headphones myself. My customer was looking for a suitable spkr to use with it last I heard. Does your AK use the short-pin "twist" type 01As. or has the tube sockets been changed to accept longer-pin types? I may have some good spares here, but not sure.
