Good Morning and happy new year ! I have picked up a model 69 Tube tester and I am concerend it may have some problems. Before I get to working on it can someone tell me if there is a schmatic available ? I am sure it has some old Caps or resistors that pehaps need to be replaced as preventivive mainenance .

Kind Regards,
