The Ultimate Marantz, Superscope, UNIX Boombox Thread

Hello. By coincidence, I found this forum, browsing the Net for Superscope audio. Since 5 years, I am a big Superscope fan and collected up to 54 items of it untill today. In my collection are three portable radiocassetterecorders. A CR-1200, a CR-1300 and a real boombox CRS-4003S. The last one mentioned I bought only two weeks ago. It's still waiting for some attention but it works. And it's one heavy dude, I can tell you. Three weeks ago, I made a website about my hobby. If you like you can take a look. Pictures of my CR-1200 and CR-1300 are also on my site. My website: www.superscopeaudio.nl .

The Superscope CRS-4003S:

 

Thank!! I just browsed a little. When I have more time, I will have a good and long look.

 

Just thought I'd share my Marantz MS100 that I found in a Goodwill back in the 80's. It was missing the knobs on the cassette deck and I never got around to trouble shooting the dead left channel. Otherwise powers on and works on right channel.

 

Back in the 80's80's we didn't have little cell phones with cameras. Might have just discovered why one chsnnel is kaput.... Those resistors don't look too happy....

 

I remember once the internet was around trying to find information about it but only finding one site with a photo of one that was unopened or something along those lines and that it was considered rare with a crazy asking price. I paid $40 for it at the Goodwill and at the time I was hesitant but mistakenly thought I could pull it apart and that the tuner, preamp/amp and tape deck were separate components. Was dismayed when I popped the back! Then discovered a dead channel. Goodwill shoppers like to steal the knobs off stereos as well.... Also wondered if a turntable was part of the package as the case was large enough to support one on top, plus the case has a slot that fits LPs and there is a phono input on the back panel. Guess I should hook up one of my turntables and see if it needs a preamp though suspect it's a 'real' phono input so might be good as is.

Thanks for mentioning the voltage, I just took a second look and notice the power supply has 4 settings which is unusual.

If I can get her on the bench and working I just might try and track down some knobs, granted the likelihood of finding correct knobs is pretty slim though perhaps off a dead Marantz cassette deck? Then I'll have to figure out the tape drive belt which I seem to recall was found in pieces inside the unit..... hmm starting to remember why I may have stopped several decades ago....

 

Interesting, we had a few Standard brand UHF 2 way radios at work. Your unit looks almost commercial in design especially with a PL-259 connector on back for the antenna. Screen design is interesting as well, almost makes me wonder if it’s a scope. Maranta was into that tech way back with their tuners. But it must be fairly recent as it scans into the original cellular band (locked out?).

 

Yes they are different then the ones on my Marantz receivers. This one has a very slight gold tint to it, which I seem to recall was something Marantz tried way back and they are also as you say a frosted-flat finish. The knobs on all of my receivers are shiny silver in colour, not that I'd pull ones from my working pieces!

I have some pulls from a couple of tape decks I recycled so at least I can cover the posts until I get a chance to go check out a surplus electronics shop here in Toronto.

 

Makes sense, I can't image Marantz having some sort of special one off parts run for this thing. Especially considering how few seem to be out there. Size wise the knobs on it are fairly similar in size to the ones on my other Marantz gear just the finish is different. The pulls I have from a different brand tape deck don't fit the record level posts very well, the one on the mic level actually looks proportional just a bit too silver but you have to really look hard to notice.

Guess though before I go too crazy I better see about replacing those crispy resistors and see if that solves the missing channel. I'll do both while I'm at it, since the parts place is the same place I go to for odd ball pieces maybe I can get lucky on knobs as well.

If you ever get up this way, check them out. We used to have a couple of really good places for finding weird hard to find components but this is pretty much the only one left in the area other than the mess in my basement....
