Greetings,
Having experienced a repeated condition of unlock in spite of all DC levelsfrom
the Rb Phase Lock circuitry being correct, I traced the problem to A14,the
logic ass:y. I went about to replace almost all discrete transistorsthere after
testing and discovering that some of them was leaky.No problems after that
except that I did not find an easy wayto replace CR13, a 3N58 according to the
parts list.
Any modern readily available type that will do?
All the best
