Level Devil and VOA Compressor/Limiters

C

ChiefEngineer

Some of the greatest audio I have ever heard came from old tube type VOA processors. Any of those around? Working?


Like the old level devil but not for the processing, just for the meter with the pitchfork guy.
 
I sure can remember what the VOA sounded like in 1972, and you are right.
"Yankee Doodle Dandy" that actually rattled your teeth no matter what level you had the volume set to!

Were they a standard rectifcation/control voltage to a push/pull output?

I have a 1948 Mc Graw-Hill Eng text of "Industrial Electronic Circuits" that has several pages of compressor/expander schems.
One, I remember was mentioned keeping avg mod levels over 90% for shortwave broadcast applications.
I will scan that in and post it along with the next "AM 1620" podcast on pod-o-matic.

Maybe it's just what you're looking for, if only you could get the xfrmrs. Maybe you have them, or can make do.
I bought a new cheap tube-stage compressor that makes me sound like heavy iron big modulation for $300.
Well, everything after audio is tube, but not high-level mod, and this damn-near puts my sound in that league.
