JC Penny Boombox

[algeeba]

Good morning/afternoon everybody.

I bought this JC Penny Model #681-3887 boombox for $10 at the flea market this past Sunday. Anybody know what other model boombox this is a clone of? It's heavy for its small size. Missing 2 knobs (?) on cassette door, tuner works great but cassette belts need replacing, I assume, because it plays slow but will FFWD and RWD correctly. It's still dirty but will be taking it apart soon to check it out. I feel like I need to paint those speaker grills, though. It's just so grey.

Good score, certainly worth $10.
Looks like an early Panasonic box.

reminds me on my NATIONAL-PANASONIC.
But this one owns LEDmeter instead the analog.

On the tapedoor only missing the 2 decoration srews.
Should be no problem to find anything similar.
Nice box!

HAHAHAHAHAHAHHAHA. Nice posts guys. Making me laugh a lot and that's why I love these posts.

When I open it up I'll see if there is anything having to do Panasonic to verify.

Have a great one.

Does the belt for this boombox look correct? If the belt is supposed to be flat like this, is it supposed to be the same width as the pulleys? Or is supposed to have two square belts and if so how do I determine the width of the square belts?

Also, there is a bracket that is adjustable on top of the flywheel. Is the flywheel supposed to have some play up & down or do I adjust the bracket so that the flywheel has no play yet turns easy?

Thanks all in advance for your help.

I gave one of those to Ira at the Sunshine Mix. Apparently, it wasn't as beach-worthy as the Aiko and he has already pawned it off to Skippy. Poor Skipper. :'-(

 

[Superduper]

Belt configuration and style looks absolutely plausible. It will not be square belts unless the flywheel has a groove for it. If there is no groove, and the belt is designed to ride on the flat ridge of the flywheel, then flat belt is correct. The ball on the motor pinion is correct. Flat belts have a tendency to want to "ride" up onto the high spot and it keeps the belt centered if the tension is appropriate. If it was a simple U, then the belts could have a tendency to scrub the edges wearing them out quicker. The bracket -- you should leave at the former setting. However, if you can not remove/reistall without changing the setting, then set it so that there minimal lash but not a zero lash condition. If it's too tight, it will wear the nylon pad quicker and the playback speed might be slower than normal, and it could put additional strain and current consumption on the motor.

NOT an expert here but just my guesses so take them with a grain of salt.

I understand correctly Superduper.

Adjusting the flywheel will be no problem (check). The flywheel has no groove so that makes the flat belt correct (check). I was also concerned about the width of the belt, thinking it had to be the same width as the pulleys so that it would not ride up or down but your explanation makes sense. As long as the tension is correct then it should not ride up.

dont forget to clean up the rods with a brush

or air spray, to make them spin better and pin some de ox on some

places with a cotton swab
