I own a Teac AG-2700 Receiver I can't find any information or specs about ANY vintage Teac receivers on the internet, there are no Teac receivers from this era (late 70s) on ebay either. Has anyone here heard of any late 70s Teac receivers?

Here are some pics.

No it is not rare, Teac was overshadowed by Akai, Fisher, Marantz and Technics in the 70's. The reason you cant find it is because its a peice of $hit.

Even if the Teac is rare, very few of the Recievers from the 70's are worth a lot of money, probably less then 20 specific models worth much over 100$. Suprising to some, almost none of these are from household names like Pioneer or Sony.

the Marantz 2275 is arguably the most valuable of the mass produced 2-channel receivers followed by the Mac 1900. So, most of the older stuff is not really worth much, some of it would be worth more melted down into scrap.

Seth, what are the 20 specific models that are worth more than $100? If apms/receiver/integrate all considered, also products of 80s included, out there in the used market, what are the models to check out? Thanks!

Get a copy of Orions Blue Book if you are seriously considering buying older equipment, or find someplace you can peruse it. As a general Rule, I have found that for gear from the seventies the MArantz and Mac seems to be the most collectible, for standard higher end models.. The high end Yamahas from the same period are good too, I under exagerated the 20, but it was more to make a point.. Most of the Older stuff that people think is great because they made it better back then aren't and even the really good stuff, like a MArantz 2275 won't hold a candle to my parasound dtuff that I have less then 400$ in (Pre/Power). But I do have a Mac-1900 thats worth around 350$ that sounds pretty good(with wood case :-) ) and a Marantz 1060 that I have been toying with doing some 'Black Gate' mods. Look for a piece that seems to have a decent value that you likee the looks of and listen to it. If it sounds good find some older B$O S45s or Polks (back when men were men and speakers were big) for a cool retro system.

The point should be made that even the Marantz 2275 and the 2275B are not the same amplifier. Few of the Marantz products from the 1970's have anything to do with the original Saul Bernard Marantz's products from California. The name and product were sold to SuperScope (affiliated with Sony at the time) in 1964 and shortly after that Marantz retired from the company and had no more control over the products that bore his name. Products such as the Model 9 and the 10B tuner which competed with McIntosh for the "best product" distinction were gone from the American market. The 10B tuner is the last competitive product which is most often sited as the product that finally forced Marantz into insolvency. (I can certainly be corrected on this point, but I remember the Marantz 7c being credited as the original inspiration for the Conrad Johnson products. The Model 9 is credited with being the reference for S.A.E.)

By the early 1970's Marantz product had changed considerably (to my knowledge the original Marantz company built no receivers though receivers were designed in America after SuperScope took possession of the assets). As production was shifted from the US to Japan parts bins were cleaned out and products such as the Marantz 2225B receiver used a small lamp in place of the original reisitor in the schematic. Lamps and resistors have a very different life span.

In a famous Marantz ad of the 1970's that ran on the back of Julian Hirsch's "everything sounds the same" Stereo Review for years, a charred 2275 was shown as the perfect example of Marantz quality. The ad claimed it was pulled from the ashes of the house and after the power cord was replaced, it worked perfectly. The reputation of the ad became the idea the 2275 had actually started the fire.

Though the 2275 and 2275B (70 watts per channel for $299) were the ubiquitous heart of a rocker's hifi in the mid 1970's, the quality difference between a Marantz and a McIntosh had long since disappeared. For the most part, McIntosh still supports the vast majority of products bearing its brand name. Marantz denies they made most of the product from the late '60's through the '80's.

Though I agree with Seth to the value of the Orion Guide I disagree with the actual worth of the Marantz products from the 1970's and the B&O speakers. A pair of AR3a's, Original Large Advents or JBL L100's with a Thorens 126 or Dual 1249 is far more in keeping with a retro system from the '70's.
(pay attention to the screwdriver death test and reference to Charlie the Tuner)
