Where can I find the diagram for this Western Air Patrol I just got? It is a TRF table model from early 1930's and one source I have says it's a Model 70 W172 but I can't find it under that. It uses a 280, a 245,(2) 227's, and (3) 224's. I think it was made by Gillifan Bros. but no luck there either. Any help appreciated.

If it was made by Gilfillan then you might find a number stamped in the metal on the right rear. That number may give provide a clue to a Gilfillan model or such.

Thanks Peter,
Looking further I think it is the same circuit as the Gilfillan 60 but uses slightly different numbered tubes.

Gilfillan 60 uses 26 tubes, BH rectifier & 71A single output tube. Unlike the 24A these are triodes. When looking for similar schematics 24A, 35 and 51 are similar. Even with same pin connections.

Check schematics for General Motors Model 120 and Majestic Model 20. One of these might be close enough?

Norm,

You had me going when you mentioned the Gifillan 60 used 26 tubes until I looked at the schematic and realized it used type 26 tubes. I had a momentary vision of one needing a forklift to move it from room to room.

See what you mean. Could be taken that way. A 26 tube radio would sure be something..
