Just acquired a very good looking Sparton Junior Model 410, TRF set.
I have restored the electronics and it is working fine, just need to do an alignment and repair the volume control.
Many of the tubes are original! It always ammazes me that vacuume tubes from 1930 are still still test very strong.
My problem is the dial cord (which looks like a fine brass cable) needs to be strung.
Does anyone have a dial cord stringing diagram for this radio?
Any tips or comments woud be greatly appreciated. Even a photo of a properly strung dial cord would be a big help.
