Philco 46E - Testing Tubes
#5

Unfortunately, the difference between a model 46 and 46E (Export) is more than the ballast tube. I quickly discovered that the schematic in Riders I, which they claim is for the 46 and 46E, is not correct for the 46E. The filament wiring is totally different in the two radios. Parts values (original in my set) are wildly different from both the 46 and 46E parts tables in Riders.

The Philco Repair Bench states that their Philco service packages do not cover the export sets. So I am having to make my own schematic and parts identification/location chart. I took a digital photo of the chassis bottom and am identifying parts and labeling them.

The problem of course is that some of the wirewound resistors are different from both the model 46 and 46E values in Riders. So I don't know if they are bad, or just incorrect in Riders!
