Need Fuse Info For An AMI D-80

by joedol » Sat Jun 14, 2014 2:00 am

I need a little info if someone would be so kind.
I need to find out what fuse or fuses this jukebox takes and where to get some.
I'm in Texas and the box is up in New York at my parents house so I can't get any info off it.
My dad says all that is wrong with it is a blown fuse. I've been given the job of getting it working again.
It took my parents two months to get me the info on the make and model so I know thats all I'm going to get.
I'm going up there next month and I'd like to already have the fuse or fuses when I get there.
Any ifo would be greatly appreciated.


Thanks,
Joe

Joe,
I'd be very surprised if "only a fuse" is blown--95 % of the time, when a fuse blows, SOMETHING caused it--4% of the time it's an incorrect size/type fuse, and about 1% of the time, it's an old fuse. If you Dad knows it a blown fuse, have him remove the fuse and check the size, printed on it, against the "silk screen" next to that fuse post--
MOST good electronic stores sell the correct ones, also some can be found in hardware stores, and auto parts stores. NEVER use fuses of a larger value, nor a different type--
If you will read the "informational stickies" posted above, you will see places to purchase the manual--which I think you might need ---( I don't have a copy of this one)

There are no fuses in it. My ex brother-in-law told my dad that a fuse was blown and that is why it wouldn't work.
So the ex takes all the fuses out and was going to replace them but he never did.
Now the ex and the fuses are gone.

Looks like I have another problem now. I read a post here last night that said if a box has been in storage that I shouldn't plug it in. This box hasn't been powered-up in about 15 years. Its been covered with a sheet and blankets.
I figured that if I could get it to power-up and at least try to work I'd spend the time and money to bring it all the way back.

Ya, a manual will be a must if I decide to restore it. I just don't want to buy one and then find out it's not worth restoring. That is why I asked about the fuses here. My first step was to get it powered-up.

Joe,

Generally speaking--fuse posts are marked, right near the post with at least the amperage of the fuse. If there is a "SB", next to the marking, it stands for "slow blowing" type. You will need for someone to look, at yours, and see if the markings are still readable, or someone with an identicle model, to do so -- OR, the book SHOULD show the same info. Did this "ex" also take the fuse "caps"--if so, you will need to know which brand they used, to find replacements.
As for "firing it up", this should be done, at least, using a 60 watt lamp in series with the line cord--Lamp should NOT light to full brilliance. If it does, amp is probably in great need of repair !Or there is a "short" somewhere in the system. If left on, this could well result in a transformer failure ($$$) !
If you do not have the electrical skills needed to set-up the lamp in series, I strongly suggest you hire a "pro"--Ron Rich

Not sure if the caps are there or not. The box is in the cellar. My dad is 83 and doesn't get around to well these days. That's why it took 2 months to get the make and model info. I know I'll never get anymore info before I leave to go up there. Unless someone jumps in here with the info I'll just have to wait and see what I find when I get there.

Mechanically I'm great, electrically, not so much. I know the basics and the difference between series and parrallel circuits but I'm no engineer. Not sure how to do the hook up with the box. Will this work?

Cut one of the wires on an extention cord. Connect one of the cut wires to one of the terminals on a light fixture and the other wire to the other terminal. Plug the jukebox into the extention cord. Plug the extention cord into the wall. Light and box should power up. If I unplug the jukebox the light should get brighter. Will this work?

when the juke is unplugged, as in your last post the light bulb will go out. think of those pesky Christmas lights that when one bulb goes out, the rest of them do too.

OK, I see where my thinking was screwed-up.
But, will this work to check the amp?

I would install a 100 watt lamp in that circuit, if using it to check the whole phonograph--lamp may flash, then should diminish greatly in brilliance, then as the tubes warm up, re-gain some brilliance. (use a 40-60 watt lamp if amp is un-plugged). This SHOULD protect transformers-- Shut off instantly, if lamp stays bright for over 3 seconds, as there is a short ! Ron Rich

I can do that, doesn't sound to difficult. Got some more, different info over the weekend.
My dad says all the fuses are definitely gone but I still don't know if the caps are there.
He said some of the lights are what is broke. He said the box worked fine after it warmed up.
Looks like I'm just going to have to wait until I get there to see for sure what the deal is.

Well, the amp tested good. All the fuses were in it and all the tubes lit up. Most of the lights came on. Left it on for a few minutes and nothing blew up or caught fire but I didn't try to see if it would work. Didn't want to push my luck. So I put it in the truck and hauled it back home. Have a manual on the way. Now the hard part starts.

Joe,
If you did not do it already,to be safe--check that all the fuses are the correct value !! (BEFORE you do another "smoke test" :lol: )

Good idea, never thought of that. I'll have to wait until the manual gets here because not all are marked on the box. But I'm in no hurry, this project is going to take a while.

Well, I'm back. It's been one hell of a 2 years I'll tell ya. Finally got time to do some more checking things out on the box.
Looks like the amp works but I can hear a hum from the speaker so it probably has a short in it somewhere.
The box also has quite a few other electrical problems that need to be fixed. More than I feel comfortable doing myself.
I'm pretty good doing the mechanical stuff but not so much with the electrical.
Anybody know a good restoration place close to central Texas?

Ya, I saw that. There is one place listed in Austin. It also says it should not be considered a recommendation.
I was hoping for a recommendation. Also, for more than one place.
Competition keeps the price down.
