While cleaning up some garage space (yes, so a Car could go in there) I came across a cache of some things I knew I had and one thing I forgot. A 2 tube module.from George A. Philbrick Researches Inc. It's a GAP/R K2-W with "computor" tubes in it. Before anybody vomits (as regards computor) could somebody remind me who Philbrick was? The name seems familliar. TIA John A.
