What is the difference between the 425B network and the 425E network?

425E has a screw terminal designated "C" to accommodate the spade-tipped hookswitch lead. On sets with 425B networks, most of the hookswitch leads are soldered, so there was no need for a "C" screw terminal.

I drew up this diagram for the above mentioned phone.
Please let me know if you find any errors.

Awesome! I just used it to resurrect a DOA 500.
The idea that a four-year degree is the only path to worthwhile knowledge is insane.
