The Transitone TP-5-I was introduced in January 1939 along with several other compact Transitone model table radios including the TH-4, TP-4-I, TH-5, TP-10, TP-11, TP-12, TP-14 and TP-15. These Transitones were much more compact in size than previous Philco table model radios, and they all used variations of the same stuffed, cramped chassis.
Since all of those wires are of the rotten rubber-coated variety, they all need to be replaced.
I have found that the best plan of attack is to remove as much as possible from underneath and start all over from scratch. Attempting to replace one wire at a time in a chassis as cramped as this will result in other wires getting damaged while trying to reach obscured solder terminals with other wires and components in the way.
So, last night...
I began disconnecting and removing wires and components.
Tonight, I more or less finished up that job.
To be able to reach everything and replace the remaining wires, I will need to remove the speaker, the dial scale, and the pushbutton assembly. Removing the pushbutton assembly will also make it easier to clean.
Both IF transformers and the oscillator coil have been removed. Unfortunately, one of the oscillator coil terminals came off from the coil form while I was trying to remove one stubborn wire. The little wire from coil to terminal did not break, however, so this coil might still be usable. We shall see.
