Hi Everyone,
I'm currently restoring a Gulbransen Premiere model 5118Y and need some advice.
I have a copy of the service manual for the premiere , though am not sure of its for this model or an earlier model as it doesn't seem to indicate which model it covers. Thus far I have managed to get most of the organ playing but do have issues with the tibia tone generator on ‘B' where 2 footages are absent. The service manual shows a transistor for each pitch but doesn't say what the transistor value is.... hopefully someone can assist.
The rhythm unit doesn't seem to provide any audio output apart from a slight clicking which varies with the tempo speed .
Lastly, I want to replace all the power supply electrolytic capacitors (10 I think) but again the values are unusual and I'm guessing no longer available.
All advice appreciated.
Thx
Scott
