Recently acquired a Philco 84b radio. Have to rewire, recap, and replace the resistors, so I pulled the transformer too. When I tested to see if any of the windings were open and came up with the below values. My question is in regards to the low reading for the windings supplying the filaments. Based on a handful of restoration videos for this model, the reading is usually around 1 ohm. My readings are obviously much lower. This is my second restoration, having previously refurbished a curb-find Philco 41-608 that really only need to be recapped and rewired. So I'm still just a novice. Any help would be appreciated.
Primary (terminals 1 & 2): 10.2 ohms
Secondary to filaments on output tube type 42 (terminals 3 & 4): .4 ohms
Secondary to rectifier tube type 80 filament (terminals 6 & 7): .4 ohms
Secondary to the plates on the rectifier tube type 80 (terminals 9 & 10): 413 ohms
CT (terminal 8) to terminal 9: 215 ohms
CT (terminal 8) to terminal 10: 199 ohms
