Philco 643 color scheme and modification
#25

Yup...that set's going to look nice when finished...

Bob, you had asked about the speaker. The original speaker was a KR-7 permanent magnet speaker (the type with the huge magnet in back with sort of a horseshoe shape), 1.25 ohm voice coil impedance.

The original output transformer (32-7472) has a 15,000 ohm primary impedance, push-pull; 1.11 ohm secondary impedance.
