[Jukebox-list] Re: 2050 tubes

[Wesley Dean]

       Ron, way back in the late thirties Seeburg made some arcade games, 
like Chicken Sam, Shoot the bear, Shoot the Coon and such. All used photo 
tubes and thryatrons. The gas tube was a 2A4G. This was a predecessor of the 
2050, with a 2.5 volt filament. Even then Guardian made the stepping 
switches. It is assumed that the Guardian engineers insisted on gas relay 
tubes, probably because no contact wear were associated with these. Once you 
have been indoctrinated in a particular mind set, it is extremely hard to 
break out. Witness the fact it is almost impossible to curtail the ingestion 
of nutrients. Wes

Wes,
  That leads to another interesting (to me, anyway) question. Do you know 
why Seeburg insisted on using a tube rather than the "relay" everyone else 
used? Ron Rich
