Newcomb's are built like tanks and are pretty easy to fix. I have a some of the later solid state ones and they usually just need some minimal cleaning, or a stylus change to get them up and running.
Remember those Newcomb and similar Dukane players from school days as a child our family had square dance lessons. The instructor-caller had the stereo version Newcomb player. Admire that unit to this day. And it used tubes. Since it has an audio mixer-as yours does you could plug in a microphone and call or sing to the music and be heard on the speakers. So would love to have one!
We had one of these in gym class when I was in elementary school way back in the day and I thought it was awesome! We had a really cool gym teacher who would sometimes let us hang out after class and play “real” records on it. He had a bunch of his Beatles albums in the office, that’s the first time I heard Rubber Soul. BTW the dots under the platter are the fine speed indicator (stroboscope) and they’re supposed to be standing still when the fine speed adjustment (usually called pitch control but “Tempo” in this case) is adjusted properly. Nice video, brought back some good memories!
Sprague Tel-Ohmite model TO-5 is an awesome piece of test equipment. I have a Semcore RC-115 which is identical to a Sprague TO-5. Great Newcomb classroom record player.
When I was in elementary school and just getting going in electronics our school had one stereo player with two 6x9 full range separate speakers. I thought that thing was awesome! We got to listen to one side of a student's album if we did good all week.
Memories! I'm so old, we got to have our homeroom teacher read us one whole CHAPTER of a favorite book at the end of the week if we were good. So not happening today. Every child left behind and teach to the test took so much good (including learning) out of the school system.
Those are nice units, really well built. The white paper caps with ceramic exteriors like to explode, especially in TV's! I've also found with multi section cans, if one section is going, the others will be shortly behind. Cheap insurance to just change out old electrolytics if you have them on hand.
High ESR is the primary failure mode of electrolytic capacitors in modern electronics. Leakage is always present in electrolyitic capacitors. The question is the amount. There are recommendations from the manufacturers. There's even a formula. There are hard and fast or rules of thumb. Under one milliamp is probably getting into the good range.
Based on my experience, I would not trust electrolytics of that age, no matter how they read on test equipment. In use, they will experience elevated temperatures, and changes in current which will stress them differently than the test instrument does.
My favorite thing you've done yet! Reminds me of antique laboratory equipment
That was a good expitode !!
sounds great Mr. Radio especially with the Tito Puente Live at Grossingers album.👍🎶

I have scored two of them from Facebook marketplace

These were used at sock hops and school gym parties! Very nice machine!

I have two of ED -10 newcomb record players. As you say, they're very robust
Square dance callers often used these, too.
Kudos for something different.
Also it's good to get some information about the test equipment and instructional use.
Sounds nice, especially with Tito Puente "Live at Grossinger's" record on the record player you fixed!

My experience back in the 1970's, too.
And it will accommodate 16" discs, too.

I have a later Solid State version of this, It has distortion sometimes, Recapped it but it didn't help
Not sure I love the new direction of the channel. I.E. Searching high and low for the reasons & logic behind leaving old caps. Just replace them.
