Ravenswood amplifiers sought
After high school (1969), I worked for Chesapeake Instrument's consumer
product manufacturing facility in Annapolis, MD. We made audio products for the Liberty Music Shop chain (NY), and the E.H. Scott audio company, apparently the successor to the E.H. Scott Radio Company which was was on Ravenswood Avenue in Chicago. They made great radios, some with over 30 tubes. H.H. Scott sued them for trademark infringement and they changed their name to Ravenswood. I started working on the production line, and at some point was head of QC because I was an audiophile, having worked in an audio shop while in school. So I knew how to use test instruments. Ravenswood's FM tuner and stereo decoder were designed under contract with Dave Hafler (Dynaco) and were pretty good. I'd align a hundred units a day sometimes. Products were made in batches, amps one day, tuners, the next. We even had a reflecting speaker system that reflected sound off the wall (predating Bose by twentyyears). As far as I know, only two ads appeared in High Fidelity magazine for our product line, then nothing. I should have known, as our checks would bounce occasionally. We had two basic amps, and I'd like to add or both to my system. Got one hidden away? |

Phil The entire line of Ravenswood "Reflection Coupled" speakers system was advertised in AUDIO magazine November 1961 issue. I quote: "Exclusive with Ravenswood, "Reflection Coupler" speaker systems have brought a radically new, exciting, method of music reproduction to the music lover. All of the speaker systems are "reflection Coupler" systems." Listed are the M-50, M-500, M-5000, M2-22, M2-32. The amps I'm looking for are the Ravenswood PA-2000 and PA-3000, |

Oops, I see the dating problem I graduated from high school in 1959 not 1969, Sorry I didn't catch that sooner. I worked at Ravenswood/EHScott/Chesapeake Instruments that summer and for another year after that before college. You guys are right on for calling me on that, but now look at the timeline again. |

An understandable misunderstanding. Kudos to Phil for expressing his concern in such a gentlemanly fashion. He has been a model of civility for other Usenet posters. |

The design arose out of an earlier attempt to make an omni-directional speaker with the multiple divers mounted on the surface of a sphere. An omni-directial speker inherently bounces sound of any nearby walls. There were many other omni-directional speakers, like Sonab that had their day in the sun too. ......... Phil |

An omni-directional speaker inherently bounces sound off any nearby walls. There were many other omni-directional speakers, like Sonab that had their day in the sun too. This was certainly an idea in the Zeitgeist. It was an era of experimentation and extravagent thought; many solutions were still likely contenders. Blumlein, much earlier, had proposed a better model, but it included a closed-system mirror-image in recording and playback. Strangely enough, Blumlein's original recording system has a new importance in the modern video-and-mp3 world, due to its mono-compatability. It's sometimes the best format for recording to two channels in a really good room, and for playback in many modern formats. And, perhaps even stranger, the 1960's ideal of omni-directional speakers is just a historical footnote. Go figure. Much thanks, as always, Chris Hornbeck |

I remember as a teenager (late 70's), a buddy of mine brought me over
to his house, where his dad had a SS Fischer setup with new Bose 901's. At the time, my audio experience consisted of 60's albums and tapes (pop, contemporary, etc music), and two systems. The first one an old tube tape deck with built in amp and speakers which was comandeered for my bedroom, the second one was my dads ultra-jap Sansui quad channel system with four multi-driver speakers (wooden grills). I had not had a chance to develop any biases or preferences regarding audio in any possible way. He played the Bose system, all the while gushing about the near-godliness of these speakers. I remember standing there, listening, and thinking "what's the big deal? My dad's sytem sounds better than this". The imaging was non-existant, and the sound bouncing thing was noticable and distracting. It seemed an excercise in sound mediocrity to me at the time. Nothing stood out, except that they coud get really loud. Now I do think the Bose stuff offers some improvement over other mass-produced audio garbage to the public, of only they would cut their prices by at least a third. My humble opinion.

That's what I had as a young man. model 720 I think, with mag phono inputs as well... little 5" speakers... the second one was my dads ultra-jap Sansui quad channel system with four multi-driver speakers (wooden grills). I bought this house from a dude with all Sansui equipment - that's all he bought at the time. And all he listened to was Elvis...

In the late 70s I remember the best sounding system I heard was one with AR9 tower speakers... that's all I knew about it. I had some Altek custom bass bins with horns, they were louder then loud... in a house... Lots of people had custom built speakers then, some people had Quad equipment... one guy had Klips Lescala's or something - they were LOUD outdoors... My favorite speakers to listen to were some Kefs I built myself... they didn't have a lot of bass but were very pleasing to the ear... my ex swiped them or I would still have them now. They reminded me of Tanoy Reveals... My neighbor lent me some 901's to try out back in the 80s, I think he was trying to sell them... I wasn't impressed... sounded pretty ****ty to me... something to stick in your love van! Isn't it amazing how many people think "out of phase" means surrounded by good sound?!?! If you want the sound of the 901's, just run your sound through a phlanger set to "comb - clock off". |

Kinda nice to see a Phil that's making sense,and that you can actually kinda communicate with. Plus,I gleaned a tidbit of info about the Bose 901's from him. ;-) |

Sounds okay,not great by any means, a few noticeable annoying/distracting flaws. ...and WWAAYYY overpriced! Guess they gotta pay for those fancy marketing slogans somehow. Now I do think the Bose stuff offers some improvement over other mass-produced audio garbage to the public, of only they would cut their prices by at least a third. |

The building is still there and I think there's still a stone in the top of the building with the logo for Scott's "World Record" radio (Scott was the first person in New Zealand to ever receieve an US radio broadcast). Nowadays the building's gone condo. They made great radios, some with over 30 tubes. H.H. Scott sued them for trademark infringement and they changed their name to Ravenswood. Which is a bit odd as EH was around before HH was. -- Ned Carlson SW side of Chicago, USA www.tubezone.net |

Which is a bit odd as EH was around before HH was. -- Ned Carlson We thought so too, but two factors entered the pictu EH had been inactive several decades and the trademark law requires continuing use in interstate commerce, and also, that HH had made a name in a specific category (hi fi audio), while EH built receivers. If I remember correctly, we could have continued using the EH Scott name, but only for shortwave receivers. If you go to the Department of Commerce website, you are guararnteed trademark protection only in a defined field of commerce, and must have used the trademark in interstae commerce for a period of time before seeking trademark registration. That;s why you can have Ford Modeling agency, Ford Motors, and Ford Electronics. |
