HP 97S I/O transistors replacement
Hello everyone! A week ago I got the HP 97S I / O calculator. From the calculator there was a wire without a plug, from the case where the battery compartment, it was connected to the mains 220v for 1 second, the screen caught fire, then the wire was pulled from the power socket. Now we are repairing with my master. There transistors were out of order: M152; M141; M211. I need their technical data to replace. I have a service manual, but I have not found the technical parameters of transistors. I very much ask you to help, since I do not have such opportunities as you. Thank.
