Remove the hardware from the control pots and gently push the board out allowing you to flip it over to get access to the component side. The 2270 is increasing in value, and is a nice receiver. This site's purpose is really to restore the primary audio path through the amplifier to provide better security against a future component failure due to failed electrolytic capacitors, and as a result move toward a receiver that is closer to the original design specs. Not only that, but pushing your amplifier section into clipping is also the biggest reason that amplifier sections fail. I will try your suggestions on my settings.

Thanks to my vintage receiver collecting hobby, I now have many others to readily compare it to. I replaced mine in 2006 and two are already burnt out. I went back into the shop and saw nothing.

Yet I heard recently that Superscope was involved much earlier than that. Stations broadcast this signal as part of the normal audio signal, but encode it so that it is above the range of human hearing. You must copy the image to your own server to use it. Then, knowing the answer, you can make an intelligent decision about what to say to whom. In a more rural situation, where you're trying to receive stations that are further away in the first place, using the attenuator can make an otherwise listenable station unlistenable - but if you're suffering from severe interference, this may be your only option.

I believe it is fair to say that there is some road to travel yet. My nova 8s never did this. If yes, you can be sure, yours was an engraved or at least a champagne faceplate. I will be starting with the power supply and moving through the receiver and finally ending with the power amp. It sounds great and all the lamps even work.

Saul Marantz died on January 16th, 1997, at age 85. The Marantz plate on the back that has the serial number stamped on it was missing as well. This time the new owner was Philips in the Netherlands. I'd go as far as saying, it would get pretty expensive if you were trying to buy a piece of current gear to match some of the Marantz stuff. Sold through Nippon Gakki in Japan aka Yamaha in 1967, with wood enclosure. I did replace the crossovers with some from Bob Crites, and that did make an improvement. And you should refer to qualified personell with the required tools to perform the alignments you don't have them, ok? Any other clues to look for?

As far as I know, there are very few, or no, stations using Dolby processing at this time. Also, some models used potted solid state modules for output sections. Here is why that is useful: The sounds that most people can hear from their stereo are created by speaker surfaces that are being forced to move back and forth by precisely controlled positive and negative surges of current driven through them by the audio amplifier.

Make sure the unit you get has the parts you need, too. I wouldn't know about vintage Pioneer, but I found out tonight my kid brother just put his clean 2226 on eBay. The tuner carefully filters that signal out once it has been used, so not only was it above the normal direct range of hearing in the first place, it is completely removed from the audio by the time it reaches the amplifier. Basic circuitry is the same as Model 2, rationalized for use as multi-amplifier. A half power bandwidth of 10 to 100,000 cycles per second guarantees solid bass and clear highs. But the high end market is far more well developed and it is one in which products are arbitrarily priced at a level the affluent consumer expects and the cosmetics and advertising are used to build up to that perceived worthiness.
