Wanted:
I have been looking for a 'Sphinx project 14' or a 'Sphinx project 4' repair manual for a long time? Possibly for a fee, Do me a PBje if you know something, get well rewarded!
I have the following questions.
How and where do I measure the bias and dc offset and what is the standard setting for this?
Test procedures etc? Schematics?
