Late last year I picked up a old Superior cross bar generator , I replaced the caps in it and I got the VHF section to work .
But the ocsillator for the bars is still not working , after lots of time spent messing around with it .
I have traced it down a resistor in the oscillator that it dead .
otherwise every thing checks out .
Any suggestions on this color code ?
It is a odd circuit ,there is JAN type 7193 wired up as a rectifier , and 2 , 954 acorn tubes , one as a transmitter , and the other one used as a oscillator to produce the bars .
Superior must have got a load military tubes .
the one end is silver , next to the yellow
To start of with black would be odd , would'nt it ? considering black is 0 on the first figure .
If I would start with yellow , it would be 470 ohm .
whats with the exrta colors ?
