Anybody Use Jukebox Amp?

Someone just gave me a ratty tube Wurlitzer jukebox. Some of these amps have RCA audio in jacks. Has anyone tried to modify one for home audio?

I've never seen a stereo jukebox amp myself. The ones I have worked on are very similar to a Fender champ. Rectifier, power tube and pre amp tube, Basically a 5 watt SE amp.

Sure! I am currently using two non modified Wurlitzer mono blocks for stereo for my barn stereo. Organ and Juke box amplifiers are great for hifi audio.

There are all kinds of stereo Juke box amps being used for home audio use. I used to have a Rowe-AMI stereo 7868 push/pull Juke box amplifier I used for years as a stereo base amp until I sold it a few years back. I have regreted that and miss it and am looking for another one
 
So..jukebox amps. Here's a can of worms I've had to dig in because part of my day-job is servicing jukeboxes! In fact, I rebuilt 3 Seeburg amps (two tube and one early SS) and a Rock-Ola tube amp just last week.

Can you use these for hi-fi use? Sure. I know of at least one guy on here who guts them and just uses the chassis and iron to build new amps. Sometimes this is necessary...for various reasons. Sometimes it's not.

So the truth is modifying them for home use is largely just feeding them power and input. This isn't always straightforward. Wurlitzers typically need to have the "junction" plug jumpered to operate out of the box; but that's largely it. They're big, heavy...and depending on the type; I never found them to sound exceptionally great. They were going for good sound...but I'd stop short of saying they were going for audiophile grade.

If you give me the amp model number, I can tell you what it needs to have done or if it's not really worth messing with. AT the very least you have a set of good iron. If it's like most of the Wurlitzer boxes I've seen...it's a 6973 based amp.

Is this amp mono or stereo ???

50's Wurlitzer's used the the Cobra cartridge A capacitor based device - you would need
to modify for line in.
 
Seems to me a Wurlitzer juke box amp should be inside a Wurlitzer Juke box. Someone restoring a Wurlitzer Juke box may pay a premium for it in order to have the correct parts. You could potentially buy something which is going to serve your needs better with the money. Those old Juke boxes were so cool with the bubbles and the 45s, that I would tend to want to help keep the remaining units Alive and working. This is my opinion and I represent it as such. Obviously you own the amp and can do whatever you want it.

It's actually pretty rare you need to find an amp...that's usually only after something like a transformer has blown up or the thing was pulled out of a lake. As long as the iron is fine...most of the ones worth rebuilding can be rebuilt. I've seen a number of those Wurlitzers get trashed and the guts parted out. They're sometimes more of a hassle to restore than it's worth...or sometimes...just costs more to restore than it's worth.

Hi, It's a #2810 juke.
 
I have a Seabreeze model A100 amp. It's single ended but the label calls it a stereo amp? DId they use 2 amps in these jukeboxes.

A100 is not a valid Seeburg amp...but they did make a 100A jukebox.

It was a 78rpm unit...so it was mono. ItsI probably a later amp as you could plug any number of Seeburg amps in.

They did make a mono amp that could be upgraded to stereo by adding a second module to the other half.

There's a model on the ampifier itself. Like MHFA1 or SHFA. This is what you have to go by.
 
It's a Wurlitzer #2810. Since it was given to me, I was considering it a source for a low cost tube amp. It has keyboard issues and taking up the middle of my home bar. Weighs about a ton too. Just considering my options. I have a nice NSM CD box and prefer it. 1500 songs versus 200 on the Wurlitzer.

Get some DEOXIT Pro gold and spray the keyboard contacts .
 
Not that simple sadly. The previous owner allowed someone to work on it. Looks like he tried to recap it. The guy said it began to smoke. Guess I will try to look at it this week end.
