I need some wisdom on ind coils.
I have a fair handle on the simple 2 coil ones. they are side tone i believe? early type.
then anti sidetone, 3 coils, mostly anyway...???
now, I find in my Leich deskset, a coil with 5 terminals, and all very different values than what i am used to seeing.
Am I lookin at a CB phone here? or just a busy ind coil on a LB phone?
I have 2 Leich 901 crank phones, but this one, "with out a sub set", leaves me guessin whats goin on here.
any help would be great.
Thanks

Leich did use some coils of some universal type, working on CB and LB, I guess pictures and values may help some. Generally LB coils has a winding with low resistance for the transmitter circuit.

Yeah, I get that far...but the others on this one are 19 ohms,420 ohms, and 440 ohms.
cant wrap my head around all that. lol :o
here are a couple pics. it looks like a nice phone, hope to get a sub set on it soon, and use it!
