Label photo and commentary below courtesy of Earl Almdale. While reconditioning this one I found that it had as shown in photo a complement of 5 tubes. A 12BE6, 12BA6, 35W4, 50C5 and 12SQ7 (8 pin). However in my riders schematic, it shows the same tubes except the 12SQ7 it shows a 12AV6 a 7 pin tube. So I ordered a Sams schematic which also shows 5, 7 pin tubes. The tubes do the same thing electronically however it does show that sometimes to save money, Use up old stock, or because of availability problems manufactures would use a substitute part something you have to watch for. Also there is no substitute for a good tube manual and take a schematic or manual with a grain of salt. |

The
"Archives" are maintained just for fun by Steve Adams at the Radio
Attic. When cabinet material or color differences are apparent or suspected in donated photos, I have included additional photos of certain model numbers. Due to time constraints, I must rely entirely on the accuracy of information supplied by contributors with their photographs. As such, no guarantee is made that the model numbers presented here are correct. Images may be used
