![]() ![]() ![]() Here is the PSU Schematic: I Measured all the voltages at the transformer secondary and every value is spot on. I guess I will have to try to measure the voltage rails using the 2160A schematic hoping that the schematic is similar. Also I searched quite a bit on the Web for service manual/servicing info and schematics for these models and had no luck. Does anyone have the Service Manual for the BK Precision Model 2160? Tried to contact BK Precision, Elenco, Pintek. I would like to start by checking the PSU voltage rails but without the schematics or service manual it's a bit hard since I dont see any test points or voltages silkscreened on the PCB's. I guess that means that both the Horizontal and Vertical circuits are not working properly. The unit powers up, but there's only a fixed Dot in the middle of the screen. I guess my unit it the 2160, as I was able to get some service docs for the 2160A and the PCB's layouts and component numbering are different. There's diferent BK Precision 2160 models, theres the 2160, 2160A and the 2160C. ![]() So it would be great to have some of you help, if you can spare the time. I work mainly in pro audio electronics and have no experience in oscilloscopes repair. Hello My oscilloscope is in desperate need of repair. ![]()
