Re: [Rollei] What did you do in the war? (long)


Nah! There were two track stereo LPs which came out shortly
after the LP was introduced.  Loooong before the Westrex
system.  It required a TWO HEADED TONE ARM!.  The
Westrex system was shown at the NY Audio Fair in 1953.   And
again in 1954.  Both at the Hotel New Yorker.

BTW, I have one of those 2 track blue LPs.  Bagpipe music.
