Hi,
If your on this forum you probably wouldn't mind finding or owning an early 60's Marantz 7c preamp. I wouldn't mind finding one in an old barn. Maybe they could (stage) that scene on American Pickers and find one for 20 bucks and give you guys an elevation in your blood pressure. No Viagra needed.
Well it must be the beauty factor in vintage audio that predominates that grabs most of us. Maybe it's the build factor and pride that goes with the Hi-fi object.
I say this because there is a copy of the Marantz 7c's circuit in a bare bones box and plain Jane knobs but with superior jacks,caps, resistors,switches ect...that if it is true should out perform an older stock 7c without a total replacement of parts like some of us old guys!
If my copy/paste does not bring up the link, go on ebay and type in Marantz 7c preamp kit. It costs a 130 dollars average, there are a few sites with this preamp. If it does not maybe one of you could post the site....thanks in advance....from all of us.
I just wanted to see what your ideas are.
Mike Samra, move very slowly now....you know the innards of a McIntosh better than anyone in upper state NY. But how much of your audio dollar goes into the beautiful dark glassed chassis with those glowing luring Mac colored lights to match?....Hope your backs better Mike.
To me I think the H.H. Scott tube tuners have that certain elan, I learned that one in yesterdays crossword.
Here goes.....I'm going to hit the paste button.....thanks Mark Korda.http://www.ebay.com/itm/like/112218810752?lpid=82&chn=ps&ul_noapp=true

Hi, those were all great responses. There was 1 picture of the layout of that Marantz circuit copier that showed the layout inside the cabinet.It reminded me of the picture of the PrimaLuna amp shot in Stereophile a couple of years ago...very neat and the wiring looked like Vladimir Lamm soldered it.
Sometimes when I get a Stereophile or Absolute Sound in the mail and look at the latest artistry of the latest amps ect... I wonder if I showed a non Hi-fi friend the picture of the component if he or she could even tell me what the object is.....have a merry Xmas...Mark Korda
A vintage piece is the sum of it's parts. The original uses a number of discrete components that in today's market would be shockingly expensive. A carbon film resistor today costs ten cents where the many of the ones in the 7c would run around 5 bucks - ouch! Then you add the REAL point to point wiring where today you could replace 90% of that wiring with a single PCB.
Unfortunately the debate of vintage sound has come down to just worn out parts and out dated material technology. No magic just worn out parts and some very expensive time consuming hand wiring. The debate of new parts materials vs vintage, well that's an entirely different argument.
Now what I REALLY wonder is if those designers and builders had access to today's parts material would we still have that same sound????? My guess is no. It would sound like any other high end audio piece today. However!! those engineers however did try and "voice" a piece and had more of an appreciation of "true music" than today's engineers.
You shouldn't paste it into the message box, Mark. Paste it into the "Optional Link URL" box and then hit "post message." Don't worry about anything else. It will automatically create a link.
So it doesn't look like a 7c, it's circuit is not like one either, neither are the parts?
There are dozens of opinions on these things
on the web including Jadis clones and McIntosh C22 clones etc.
I'd save my money. I read just last week on a blog someone's experience with one of these things where circuit errors on the PCB and part choices had to be corrected. I can't for the life of me remember where now.. but if I do recall it I will post it.
If it doesn't walk like a duck and smell like a duck well then it's not a duck!
Can't possibly be a Marantz 7 - where are the tone controls, filters, etc? It also says M7 in the description - trying to say it's the same as an Audio Note M7? If so, those two circuits are very different. Personally, I'd stay far away. If you like the look of vintage, buy an old Dynaco PAS and update it.
I agree. Even if the circuit is accurate, it is line stage only, and the circuit was designed to accommodate tone controls, tape loops, etc. If you don't want those features, a much simpler circuit would be more transparent. If you want those features, as you say, there are modern PAS kits that will have them. If you don't want them, there are also PAS redesigns that optimize the circuit to be without. These are by respected companies and designed by people who know what they are doing.
