[karl dalen]

Hello you hetrosexual faaags! .........again!

On semiconductor are also selling the compander series from philips
old designs but there is not much to chose from and since the factory 
fire be happy that its awailable at all, however if you are about to 
build a vocoder to your audio setup concidder the SA572, its dual gain 
cell and dual rectifier with setable attack and release times makes
it quite usable in such a design!

One SA572 does two channels so by eight makes 16 channels for less
25 usd!! Add the 32 24db BP filters and all in all a patchable 16ch
vocoder for less then 50-60USD!! Thats very cheap!! 
(well it depends on the cost of the capacitors offcourse!)
But asume a quality vocoder for less then 60 usd with standard fet OP's!
