that is`nt there any more to get the proper fit and size needed for a replacement. I swear (but not literally) that these guys don`t know what I`m trying to get at in explaining what I need. Maybe you could some day even make up a short video on how to estimate a belt size by the string method and then measuring it the proper way. I keep trying to tell them and tell them but like I said, we just don`t seem to be on the same page as to what i`m talking about. PLEASE HELP ME. Ed.
For a question such as this you should send me a PM via YouTube. I can better help you that way. BTW, your procedure is correct for measuring. I think the vendor is confused. Send me a PM and I can return with links to a place that will help you out.
Thanks for the belt replacement video suggestion. Good idea!
could`nt send it to them for a refit. So I tried to tie a string around the drive system and took it off to measure it. I measured it to be around 7" long, but when they sent me the replacement belt it was only about barely 3" long. So I sent it back with a note explai ning it was the wrong size and they said they could`nt understand what I was talking about that it WAS 7" long. Now maybe I don`t get it. but could you please explain it to me as to how you measure a belt
Dear Clydesight, I was wondering if you could tell me where you get your replacement tape recorder drive belts from. I`ve been trying to deal with an on line company called Vintage Electronics, and they are aggravating the heck out of me by not understanding what size of belt I need. I`ve emailed them over and over, and they still don`t seem to get it. I need a belt for an R.C.A. Victor large tape cartridge tape recorder and the belt it took was melted and deteriorated and
I got a B&H 2433a (early 60's solid state) that I'm looking to clean up (already works and is relatively clean). What types of oil are suitable to lubricate the motor(s)?
I prefer Marvel Mystery Oil. It is a cleaning and lubricating oil that works at a range of temperatures. It is red in color and a thin oil. You can get it in most USA hardware and auto stores. Google Marvel Mystery Oil to see them on the Web!
I was meaning something like: what properties do you look for in an oil for this purpose? See, I've got quite a few oils, around the house, already. I just didn't want to spend any extra money. I got wd-40, 3-in-1, and teflon infused, high-purity , synthetic (bought from radioshack).
Well, those are all good oils, but they tend to be very general purpose. WD-40 is great for cleanign and polishing cases and plastic, 3-in-one is a bit thick, I don';t know the RS oill. The Marvel is designed for car engines and as a gas additive. It works very well under high heat conditions. Some TR motors get very hot, and the Marvel doesn't change characteristics with temperature. It isn't expensive. If I didn't have that, I might try the RS oil. WD tends to dry out.
Thanks. These simple AC squirrel cage motors are not hard to disassemble for cleaning and lube (ALWAYS UNPLUG THEM FIRST!) especially compared to the fussy little DC motors in battery machines.
The only trick is aligning the bearings when you put them back together so the rotor is completely free and unbound. They usually have locator pins to ensure the motor goes back together just the right way.
VERY nice design on the inside of this tape recorder! Those guys sure had unique solutions for 1955! I am not surprised why this reel to reel cost so much when it was new!!
It just fascinates me how this machine was built. It's more like something out of avionics design than audio with all the modular parts. Great video. :) JC
Amazing to see how it all works inside. That machine is defiantly ahead of it's time. I'm surprised they used induction motors to turn the reels,wouldn't that would put a lot of tension on the tape?
It seems that B&H were think of things that many manufacturers would not adopt until more than twenty years later!
My AKAI X-200D also has three motors in a similar arrangement, although there are no solenoids or the like, but the way the motors drive everything is indeed similar. I shall have to do a video of that fine machine later on.
Wow, you got to see this before YouTube even had it processed or linked. You are FAST!
Yes, please do a video on your AKAI machine. A lot of people love AKAI's and I am sure they would be very interested, (as would I) to know how one of them works.
Thanks for your very FAST comment and rating! You are now officially faster than a 1955 Bell and Howell Tape recorder. That distinction will get you a ride on a city bus, as long as you also have the proper fare.
Sometimes I come online at the exact moment the video comes up... I seem to recall that this isn't the first time I've done this... It last happened on your Mood Essay.
The AKAI is at the to of the list just behind my Sony TC-230... I will do a video as soon as I get my camera back.

Thanks! Since I started this series, I have been able to fix the vent system so it is no longer noisy! The drive wheel still rattles though.

@CooolDudeClem,
Thanks. The 4-pole induction motors are strong once they get up to speed, but until then they are relatively weak.
This is why they need to be so free, or they can't get up the strength needed even to pull a full reel of tape!
Also, when freed (as I did with the re-lube, they present very little resistance and no back tension at all.
It is an amazing design, and somewhat counter intuitive. But, they made it work.
