What a surprise, I have a weak spot for vibes and always pick up any jazz albums with vibes on them when I'm out digging. So nice to see the inner workings of a vibraphone, thanks!
You will not get an appreciable speed increase by overvoltaging an induction motor. The listed speed is usually the nominal speed, a "tad bit" lower than the synchronous speed, which is 3600 divided by a small whole number (3000 respectively divided for 50Hz countries). Without increasing the frequency of the power supply to the motor, or having an external source of power to spin the shaft faster, you can't exceed or even reach the synchronous speed. The former case could be achieved by a VSD. In the latter case, the motor would act like a generator and backfeed power to the network once synchronous speed is exceeded. The "vibra" part is a misnomer because it is not a vibrato effect, but between a tremolo and LFO controlled resonance. But it sounds nice!
That's really cool. Congratulations on persevering and not letting the motor issues defeat you. I didn't even know a vibraphone had a motor. The instrument sounds great, too. Is it a keeper or will you sell it?
Hi Steven, it was a Bodine Electric Company Model NSP-11R speed reducer motor. 1600 RPM, 115AC. Important: 2.7 Torque, the model will read the same but the torque values change

I'm glad you enjoyed!!
Beautiful instrument! Nice repair job
Thank you!!
Between this and your lapsteels you could make quite the hawaiian album 🏝️
LOL, I don't have any lapsteels though 😋

Yes
home run, nice work!
Thank you!!
Great work as always. I love anything vibe or fender Rhodes. that bell tone is so nice
Thank you so much!! My dad said it was a giant rhodes lol
Cool project! We'll done.
Kroil and flitz are both top notch products. Semichrome polish is also as good if not better than flitz.
Agreed! Thank you!

Thank you! I think I'm going to make some more videos with it hopefully and then see what to do with it. Not the smallest instrument lol
Thank you for this! Do you mind sharing where you purchased your replacement belt?
No problem, I got it off Ebay. I looked up "Jenco Vibraphone Belt"
@@analogemma Thank you again! Looks like there are no current listings. Do you mind sharing the approximate circumference of the belt you bought?
I have a jenco vibraphone but no motor. Can you tell me the specs of the motor that it came with??

Okay! And do you know the final RPM after the speed reduction?
