Heroic Restoration of a 1948-52 Kalamazoo KEA Amp with an Unusual Circuit

In this lengthy and rather complex video, we will completely refurbish a truly wretched old barn-find 1948-52 Kalamazoo KEA amp, with a very unusual method of Phase Inversion. Virtually every single part has to be repaired or replaced.....with the goal of turning a lost cause into a real gem. Watch to see if I manage to accomplish this unrealistic goal.....and you will be rewarded by a long-overdue and pleasant surprise during the audio testing.
In addition, we will open some fabulous gifts from generous viewers with help from Jack & KC, and put an end to percolating carburetors on the 1932 Ford Pickup. Hopefully, there is something here to please everyone.....God knows we tried :)

@@UncleDoug you guys :) None of your saucy stories in front of Jack & Kasey thanks

[@johnbarker5169]

Yes, Yes, Yes!!! on the SM57!!! I think it is definitely worth the trouble. I humbly suggest moving the mic a bit off center to get a more balanced sound; centered is generally too bright. Also, it looked a bit too close to the speaker (for my taste). I hope you will continue using the SM57 for future videos. Perhaps you can come up with a mic placement you can use consistently for all recordings. BTW: The worst thing about the camera mic is the automatic gain control and the way it tends to overload. I think you should consider recording some new demos of your fabulous amplifier collection. I would be willing to send a supply of catnip and assorted kitty treats to help entice Jack and Ollie into some additional recording sessions. Thanks for another terrific and inspiring video!

[@UncleDoug]

You're quite welcome, John. I will experiment with microphone placement and will consider using it to re-record some amps from previous videos. Thanks for your input :)

[@Echo_III]

Yes, The Big Test will be perfect. Camera mic make all these amps thin but you always say they have balls. Nice, sunday test will be perfect

[@UncleDoug]

Thanks, Russell. I will. Thanks !!

[@Bbendfender]

I agree about the new mic.

[@antibodyjeans]

Totally prefer the SM57. It adds clarity and dynamic range. Agree that it should be slightly off centre. Thanks for doing that.

[@djentlover]

Uncle Doug, The center is usually too harsh. Consider angling it so that the mic's diaphragm is parallel to the cone's surface. I find it's more natural sounding when the sound waves come from a parallel surface.

[@Cyster123]

​@@UncleDoug SM57 is the way go, definitally. I notice though some high frequency jitter in the recording. Don´t know if it´s from the metal grill or not. I suppect it being from the sample rate from the audio recording of the Tascam. When you collate the video from the camera with the audio from the Tascam. whatever export format you use should have a matching audio sample rate to the original so you won't get any digital artifacts.

[@cfreeman5631]

[@jagjet9153]

Up to and beyond your usual fine work, my friend ! The amp sounds really fine and hardly no work required...he he ! Just as a thought, the standard for rating speaker efficiency, the mic is placed at 1 meter at one watt of power. The new mic sounds great and if I understand you placed it directly in the YT feed ? That would while sounding much better which it does, my thought is to record the file separately and place it in a digital file that we could download separately from a dropbox or similar, in order to get a full clean playback to play through our own DAC without YT compression. As regard to our other project "SB swap", UPS seems not to be able to find it though all say it is coming. As usual no good deed goes unpunished. I will advise. Cool licks and Hot days in El Paso, keep your head down and keep 'em coming ! Robert aka jagjet PS the rush of fuel might even be the cause of float bowl woes as well, a vented cap might even stop the problem.

[@JeffCounsil-rp4qv]

I was thinking the same thing with the pressure build up in the tank. As the fuel evaporated from the bowl, it was refilled and the cycle repeated. Now that the super engineered heat shield is in place, and a vented gas cap, neither should pose a problem again. Even with the added motor booze to the fuel. ;-) The new Shure Mic is great! Way better dynamics than the camera mics.

[@UncleDoug]

Thanks, Robert. The method of digital recording was described in the video, and the percolation problem was completely resolved by the insulator plates and the vented gas cap.

[@eugenepohjola258]

Howdy. Old carburetor Toyotas used to have the same problem. Very difficult to start with warm engines on hot summer days for people who didn't know the physics behind. People just kept pumping the pedal resulting in flooding the intakes and combustion chambers. And all wet spark plugs, of course. There was this Lady living in my parents neighbourhood. She could not get her Camry to start. I saw my chance to excel and asked if I may try. Sure enough that was ok. So I pushed the pedal to the floor and turned the key hoping that the throttle open the excess fuel would vent out and the engine eventually ignite. Bull's Eye. After, say, 5-10 sek.s the engine fired up with a terrible blast from the exhaust ! The Lady got startled but she was so happy when the engine had settled and ran smoothly. Man ! Did I feel like a million dollars ? Yes Sir ! Regards.

[@UncleDoug]

Thanks for sharing this tale with us, Eugene. The old "hold it to the floor and dry out the cylinders" approach was always a good move back in the old pre-fuel-injection days.

Hey Uncle Doug! Just wanted to tell you how much I’m enjoying your videos. I took radio and tv repair in trade school back in early 70es. I ran little repair shop until got on regular with postal service. I also play guitar in bands as a side line for many years. So now that I’m retired I’m enjoying playing guitar and doing hobby electronic work. I really love the teaching videos. They remind me of school and has been a great refresher coarse for me. I also Love the pets and hot rod video as I’m a pet and car lover. So keep on picking and saving those old amps.

[@UncleDoug]

Will do, Lanny. Thanks.

[@DoctorCalabria]

The SM57 is an improvement. Mic placement experimentation might help de-emphasize the increased high frequency response. The auto gain of the built in camera mic is eliminated as well with the new set up. The carb nut count reminds me of the sponge count we do in the OR, although dropping a nut into the manifold would be far more calamitous IMO;) Thanks for the amazing service you provide. The few dollars spent on Patreon is the best ROI out there!

Greetings from Canberra, Australia. The Mic is a winner. Thanks for all you great videos Uncle Doug, Jack and Ollie.

[@dougsharrott]

Pro tip on the 57. Aim it right at the seam of the dust cap and you can go 5-10Deg off axis. Will give a fuller sound (dead on the cone will result in a LOT of high end). Slightly off axis will help with plosives. Also 1.4X the cone diameter away will allow the full frequency of the speaker to be picked up (no need to angle the mic then). Great vid!

[@UncleDoug]

Thanks for the detailed info, Doug.

I came here for the tube electronics; but your craftsmanship as a woodworker, metalworker, automobile engineer, musician, drone pilot and cat enthusiast make for highly enjoyable, entertaining and engaging viewing.

[@UncleDoug]

Wow, thanks so much, Ross. You have made our day :)

[@pharmerdavid1432]

What a beautiful amp - I have a weakness for round speaker cutouts, and that speaker grill is classic! "Kalamazoo" reminds me of the "Kalamazoo Bass 50" I used to have, with two original C10N Jensen speakers), two EL-34's, and big transformers. That was one I shouldn't have let get away - the guy who sold it to me said his band mates begged him not to sell it...

[@eatshitgoogle]

I love the SM-57 instead of the camera mic, even if just to do away with that ringing sound on high notes the camera mic usually presents.

[@djfrank59]

Another premium repair/restoration video like always!. I'm going to add my 4 cents in now :) First, the fuse being under the chassis is a great inconvenience...however, Having BOTH, and internal as Well as an external fuse has a major advantage. It avoids the temptation for the owner to install a larger rating fuse than what is supposed to be in the amp. Many times, I tend to "Kid Proof" the amp when I discover a larger fuse other than the factory. i install an internal fuse slightly higher in rating as not to make it unsafe, but will still blow if someone does the tin foil fuse in the outside holder, which we have seen more times than we can shake a stick at. OK, the SM-58 Dynamic Mic...Its a winner by all means, and really shows off the actual tonal quality of the amp. The SM-57 has been the go-to mic in recording studios for ages when it comes to micing a guitar amp. I've been using the 57 for decades in the studio. My choice for larger cabinets sometimes is the EV RE-20, however there's about a $350 difference. The 57 is an excellent all-around mic for a guitar amp. I recommend staying with it for the demos. Stay well, and hope all is well :)

[@UncleDoug]

Thanks so much for all your helpful comments, Frank. Yes, we are all doing just fine. You too, I hope.
