COMPLETE RESTORATION SERVICE---MARANTZ 2275 AND OTHERS

NOTE: READ THIS FIRST!!! This is a service listing. We are offering the service required so a Marantz 2270 or 2275 may be restored to premium condition and may have very high performance and reliability. If you have a 2270 or 2275 and would like for it to be as close to new as possible, or if you enjoy reading my listings, then read on. If you are looking to purchase one of these receivers, most of the ones you might find out there in the world need this same service before they will really perform well, so read on. Note also that this same listing will apply for similar Marantz receivers, so if you have a 2265 or a 2265B, or perhaps a 2285 or a 2285B, the work is the same, and this listing will apply. I do all of the Marantz receivers but it is difficult to write a listing for each and every one, so if you have a different Marantz, then call and tell me your model number and symptom, and I will tell you your best options.

Okay, so you have this really pretty Marantz 2275, Uncle Otis went to his considerable reward and left it to you. You tried it out, and it almost works. The channels come and go, the radio is hard to tune, it is making some funny noises, and some of the lights are out. In spite of all of that, it has its moments.....when it feels like it, it will briefly sound WONDERFUL, so you suspect that it would be really nice if it actually worked all of the time. It is rather like being at the really cool scenic overlook on a foggy day....you just know the view would be dynamite if the damn fog would just go away. So you trundle the receiver off to "Television and Washing Machine and sometimes Stereo Repair Superstore". You tell Gomer about it and He says "Well, I don' know, it's kinda old.....mebbe we can kinda look it over and see if we can tell 'bout it". You decide that another alternative is necessary. That alternative is here. Circle Stereo has serviced Marantz's of this style since they were new, so we know them VERY well. Since any stereo receiver of anywhere near the quality would cost you much more money, you MUST get this one restored.

Ok, That sounds good, you don't doubt that the Marantz has really good vibes hiding down inside, besides, you know that Uncle Otis up in heaven would be pleased to know that you liked his receiver well enough to restore it (and he will know). Perhaps you are a bit hesitant though, you figure it would be just your luck to have the receiver that has some screwy problem so it doesn't work out well. That doesn't sound like much fun, so this is how we deal with uncertainty. First, either send me an email, or call at 512-294-5635 and tell me which model you have. Tell me what it does. I will either tell you that it sounds routine and we should just do the restoration service, or I will say that it is uncertain and we should instead run a diagnostic. In that case, go to my eBay store listing "DIAGNOSTIC SERVICE---VINTAGE AUDIO COMPONENTS" purchase that listing. You will get the pleasure of finding out everything you need to know about your Marantz before you are committed to the service. Note also, that if you have a different Marantz or for that matter even a different brand of vintage receiver, the DIAGNOSTIC is a good way to get started, and it keeps the whole matter neatly in an eBay context.

Now, some of you reading this might be curious as to just what a "Complete Restoration" is. Since it is unlikely to be magic or paranormal, there must be a bit more detail available. By all means, let me give you a sense of the procedure. The first step is bench evaluation to establish the starting point. We test it on all functions, to see what works, and what doesn't. Frequently, it is a good idea to run the machine for a day or two to see if it has any intermittent failures. Once all of this is done, we know exactly what is needed. The next step is to disassemble the unit down. We remove the case, the front panel, all the knobs, and are left with the chassis alone. At this point, it is appropriate to clean and deoxidize all of the switches and controls and the tuning capacitor. Then parts replacement begins. The critical areas on stereos of this vintage are the regulated power supply, the amplifier section, the phono section, and the protection circuit. In all of these sections, the electrolytic capacitors are replaced wholesale. These capacitors over time change their value so their replacement makes a big difference in both performance and reliability. Besides the capacitors, various models contain transistors which have high failure rates, so these are routinely replaced. The entire unit is scanned for bad solder joints, especially in areas where it runs hot, and these are re-soldered. When all of this has been done, the overall function of the unit is confirmed to be within spec, and alignments are done. The unit can then be burned in for a day two to confirm proper function over time. This is done before reassembly so everything is still accessible. By this point, we are satisfied with the overall function of the unit, so it is time for lamp replacement, cosmetic cleaning, and reassembly. The unit is should look sharp and its functional condition should be very close to original.

So as you can see, restoring receivers such as these is a pretty precise matter, and as you may well anticipate, vintage receivers such as these Marantz models are really something when they are done properly. The keys to success are pretty obvious. You have to start with a piece of equipment that was well made to begin with. Then you have to be very familiar with the inner workings of the unit in question, and also with the types of failures that you are likely to encounter, not just the overt failures mind you, but also the latent stuff that is likely to fail later. This is only accomplished by much experience. Finally, you have to have the patience to very carefully work through each and every item that requires attention. Nothing may be missed.

So there you have it, now you know pretty much how this is all done. Whether you select the complete restoration or the diagnostic, your name and address will all appear in my inbox when you purchase the listing. I will then send you an email with instructions as to what to do next. Packing is critical. We want to be sure that it travels well both ways. The warranty on service is 90 days and is available on request. So look at that cool stereo you have had for all these years and say: "How do I love Thee......". Then box it up to send it in. I'll be glad to make it like it was many years ago. Thanks, Bill
