Model 90 tone control help # 03137
#1

Hello.  I am working on a model 90 SN A40030. It has a single 47 output tube.  The schematic and partslist shows the tone control as part number 4037-A. However, the part that is installed is 03137.  I looked at the schematic for the dual 47 output tube model and figured out the wiring.  Can anyone tell me the value of the 3 internal caps? I couldn't find any documentation on the 03137.

Thanks -Jim
