[R-390] R-390 Veeder Root counter

[Roger Ruszkowski]

Ken, ZL3AA Good news the answer is on line.Out on the R390.net site are two different parts manuals.You guessed it one for the R390 and one for the R390/A TM 11-5820-357-35PTM 11-5820-358-25P Cruse the noun nomenclature until you find the description and part number.Look the number up in the other parts manual. If the two counters are not the same at least you will know which part you do need. Sent from my childhood bedroom while my library of visual reference is in storage.Input at an ergonomic work station for south paws even. Ken, all the documents are on line. Down load your self some PDF copies.  Read the AGC thread. Some of the best exchanges in years on the topic.The manual is good for part numbers and cross use.The manual also has an AGC schematic that follows actual construction. Actual circuit operation is not explained in the TM.The glass box view is very opaque, 60 years after production some newproblems are coming up as parts do get old and give it up.
