Hi Joe, I've sent the service information for the Grunow 1291 & 1297 models, I can't find the 1293. These have the Teledial and I hope they will be similar to yours. Here's the listing for the model 1291 in Bunis' Collectors guide. The price is probably out of date now but it indicates a fairly valuable set, just a rough guide.
1291 , console, 1936, wood, upper front Tele-dial, lower cloth grill with 5 vertical bars, 4 knobs, BC, 3SW, 12 tubes, AC $225.00-250.00

: I need a schematic for a Model 1293 Grunow Teledial but can't fine one listed in the Riders Index. Also, does anyone know the value of this one...it is a dandy. Thanks, Joe
