Hello All. Attempting another fix on my wife's 1965 Vox Continental. This is UK version that powers with -8.2V and Ground.
Of course these things are full of germanium transistors and a few have failed over the years. The time is going to come when subbing Si transistors is the only option.
Shown is one of the six dividers that give seven octaves for creating the tones depending where the stops are set.
Since this is a pulse divider what needs to be changed in the circuit to use typical Si transistors? 2n3906, BC557...
Thank you.
