Hi guys, I found a like new Motorola 3channel portable stereo, sounds amazing and lots of power for a portable, about 50 lbs
:lol:
When I pulls the changer to service it and regrease it, I noticed in where the chassis is and tubes there is a fuse there? What's this for? I never seen a fuse in a portable before, I know this is a huge amp in this monster. I'm sure someone knows about the sh18, I like motorola stuff. Came with the instruction manual, turntable disc manual, 3 new old stock needles and a pack of fuses, but they don't look like the normal single filament type, never seen this style before? The machine is extremely clean and new looking for a 1959 stereo. Paid 30 dollars for it.
Any help or knowledge anyone has on this model I'd be great full. Thanks.

Mike

Hi guys, no this one doesnt have the vibrasonic, if your asking what the fuse looks like, its got a tiny little spring looking thing wraped in a piece of cloth looking material? i cant describe it, noyt like a normal fuse.
What does this control or the purpose?
like i said i have a few portable machines but never saw one with a fuse in it. guess its a good thing to have :)
The same model just sold last week on ebay for 300, and wasnt no where near the condition of mine with all the extras i got with it, all the original paperwork, manual, 3 brand new old stock needles, and a pack of those odd fuses.
I will be posting it on youtube soon so i will let you know when its up.
This is the 3rd Motorola 3 channel stereo i own and they sound very nice, has mega power for a portable, but weights 50 lbs, cant imagine carrying this around.

A portable that weighs 50 pounds has to be one potent son of a gun.

Hi fi,
I had already replied no its not the one with Vibrasonic, i dont know what one that is, i think its the SH22. that came out in 1962. That would make sence because i have a 3 channel console the SK53 Drexel cabinet and it has the Vibrasonic in it.

Yes thats the fuse right there :) I just thought it was odd to have in a portable, but the amp is this thing is massive, so maybe thats why it does.
It came with a pack of 4 new unopened ones

I am aware you already stated it was not the model with Vibrasonic! I was asking what the model number for the vibrasonic portable was and the question was not directed at you personally,but rather anyone here on the forums that might now.
I tried doing a google search myself and didn't find any info.

Wow, look at how high the prices are! $210 for a portable phono, $499 for a console, etc. This at the time when a new Chevy was $1800, a Buick was $3000, and a 3-bedroom house in a good suburb was $25,000.

Boy,that sure was a lot of bread back then! I doubt too many of these went to record party's with teenagers!

Wasn't there a problem with the 3 channel system that caused Motorola to abandon it shortly?

I wouldnt take anything for them. 2 of which i have had redone and the last one im talking about here is all original. I use them all weekly, i wouldnt take anything for them, we enjoy them to much. Good thing about having 3 of this type is i have one in the downstairs family room one in my office and one in the upstairs living room, so we can enjoy them no matter where we are in the house

I can remember seeing $10,000 price tags on big screen TVs not all that long ago. The latest high tech stuff has always been expensive. Prices drop over time. In 1959, these Motorola phonographs were near state of the art. Stereo records were almost a year old, the latest high tech sound equipment.

Most all stereo records have a mono bass track. That center channel bass stereo amp is not all that different from a mono bi-amp system. It gives the illusion of having more power than it really does because the right and left channels do not have to put out any bass so there is less inter-modulation distortion.

That warm tube sound can usually be overcome by turning up the treble.
