http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5724620772&ssPageName=ADME:B:SS:US:1No affilitaion, yadda. Just that I grew up thinking Muzak was an evil of the 60's and 70's.. built from solid state..
This thing looks like it can drive a number of speakers, say, to provide brain-numbing 'music' to an office / shop? Oh the horror.
Follow Ups:
the stuff that Muzak and other non-commercial music providers used were high-duty-cycle amps, designed to run 24x7 in less than ideal conditions. The older tube stuff wasn't too bad but the ability of SS stuff to not need the periodic servicing made them a no-brainer to the bean-counters at the banks and department stores who was them as a necessary evil beyond the drek that was played through them.I know. The owner of the stereo shop discovered that he could go around to the nearby small towns of my college town and sell off Muzak, thereby adding to his sales of conumer receivers and amps. He just sold them on using the local FM easy listening station. I ended up having to use much higher quality amps when the Pioneers and Technics receivers - the same ones some of you pick up at yard sales - died.
One of the things these PA-type amps did was to have 70.7 volt outputs which allowed *lots* of speakers to be tagged onto the output and accomodated the lengths of wire runs without substantial losses. You see this feature on a number of Mac tube amps but that sort of thing was dropped for most consumer gear.
In short, Muzak systems had some different requirements not seen in the consumer amps.
Cheers,
I had a pair of Muzaktube amps back in the late 50's They had all octal tubes, 6sn7's and 6v6's. As I recal they sounded pretty good after I renoved the input transformers.
I have a pair of Muzak amps made by Langevin, and they look quite similar to the Langevin 128 with a 6SJ7, 6V6 and a pair of 6L6's. For the life of me, I can't find an actual model, and they are distinctly different in layout than the typical 128. No schematics to be found anywhere either. Very well made and expensive looking for elevator music amps.
