I spotted what appears to be a Teac A-4300SX with NAB hubs.
That Dynaco was in the window of a record shop. More likely in a hi Fi shop. Inside the same store they're playing records on a cheap BSR type record player. Still it's fun to spot gear. Macintosh amp on the Piano in Hanabil's apartment.That is what I have noticed. The gear is a mismash of what they could find and throw together, not a 'system' purchase as would have been the case with a few of these installations.
I for sure did not like the what appear to be Advent speakers with the Dynaco tube amp between them and the speakers has dirt patterns on the grille cloth and these were in the window of the store. Should be clean pristine grilles like we put on our speakers.
Interesting selection of gear. Not sure when the show's supposed to take place, but I'm guessing that the Beocenter 7000 is way too new for the time period, since it came out around 1980. They probably should've used a Beogram 4002 and Beomaster 4000, or somesuch. Might've looked too futuristic, though...Here ya go, (if you don't have HBO). http://www.soundsclassic.com/rock_n_roll_props.htm
You geeks sound like me watching military stuff in a movie or on a TV show.
Shook his hand, said thanks
