TLC for Vintage Marantz Receiver in NYC Area
A few years ago, I paid a premium for a vintage (late 70's?) Marantz receiver which appeared to be (and was represented to be) in 99 point condition.
For a couple of years, it just sat on a shelf in my office where once in a while I would admire the blue glow of its dials.
Recently, I moved it into the house, where it is hooked up to the cable TV, DVD player and a pair of Epos 12 monitors.
In general, it has worked perfectly, is a joy to use, and has a nice warm, non fatiguing sound.
The left channel has developed an intermittant, staticky drop out, however. This seems to occur more often on the auxilliary input (where I have connected the DVD) but it seemed to also happen on FM.
It is the kind of thing that often goes away by slightly moving or tapping the receiver, turning the input selector back and forth, or even adjusting the volume up and down. So it is really maddening.
More maddening -- I have been screwed over in the NY area by techs and repairmen on vintage equipment and would therefore appreciate any advice - either on how I might diagnose and repair this myself, or if anyone knows an honest technician.
Here's something we rarely hear on Agon: my wife LOVES this component.
So any advice greatly appreciated and thank you very much.

The spray cleaner suggestion is not much help without some idea of how to use it. Although there used to be at least one place on the Net which told you how to clean a component, I seem to have lost my link to it. I imagine the point was that your Marantz probably just needs cleaning, especially its switches and controls. If you get some spray cleaner, open up the unit and place it in a good position to drain, find the openings in those parts, then squirt some stuff in while turning or switching the controls back and forth a few times, that may solve your problem. You can have a technician do this for you, of course, at the cost of about an hour of labour. He will probably do a better job, but you won't learn as much. Also, if the problem persists after cleaning, a good tech will already be some way towards an idea of the cause. |
Cw, I live in the NYC area. The best technician in the area for refurbishing Marantz vintage equipment is the The Soundsmith in Peekskill. They can be expensive, depending on what is wrong with the receiver. One thing that I also ask for is to have the power cord upgraded. If you don't feel like driving up/taking Metro North up there (they are a five minute cab ride from the train station), you can UPS/USPS the unit to them. The repair process usually takes a month. The Soundsmith guarantees its work as well. Sounds like you unit needs a good cleaning ... assuming you know what you are doing (which most of us really don't). There is also the possibility that some capacitors may be going and need replacing. While you are at, you should get the tuner recalibrated and the lights replaced. Regards, Rich |
