That is awesome! Thanks for sharing that.

I own a jukebox and always wondered if they had some kind of limiting in them because all singles play at EXACTLY the same level.

I wish there was more of this kind of documentation out there.

Hi,

My 1954 model Seeberg HF100R has a tube based automatic volume control in it. Its a slow responsding (attack and deacy) compressor. There are adjustments to allow you to set the degree of compression. When the record is selected and the pickup drops, the audio is muted and the compressor is set to min gain, so there is a slight fade in at the begining of each record as the compressor finds its operating point. I think this is one of the first boxes to have this feature. It was a key thing for use in a bar setting as recorded levels vary all over the place. Alot of of home users, defeat this by removing the tube responsible for the gain control (6SK7 IIRC). It eliminates the fade in problem and the audio is a bit better sounding as the circuit tends to soften the highs a bit.

For the record (no pun intended), I believe that it was the 1952 Seeburg M100C juke which first introduced the rudimentary AVC (Auto Volume Control) circuitry.
As you rightly say Mark, it utilized a 6SK7 tube.

Mine is nowhere near the vintage of those boxes.

I googled those models and they are SWEET!

Mine is a 1977 Rowe R-88. All solid state. Very modular, I bet the limiter is in the amp unit on this one.

Thanks for the info!
