GOOD EVENING FRIENDS. ITIS JULY 13, 2022. I CAME ACROSS AN ASSEMBLED CMC 707 WHICH THE OWNER OBVIOUSLY THREW AWAY. THIS NEVER WORKED. MANY TRANSISTORS WERE NOT CORRECTLY INSTALLED AS TO THEIR PINS. VERY COMMON MISTAKE. MOST SILICON TRANSISTORS HAVE THEIR EMITTER ON THE LEFT IF YOU ARE FACING THE FLAT SIDE. MOST HAVE ITS BASE IN THE MIDDLE. C945 HAS IT ON THE RIGHT SIDE. IT IS SIMPLE TO LOCATE THE BASE. PUT YOU TESTER ON RX 1. ONE PROBE TO THE BASE, THEN CONTACT THE OHER PINS.IT WILL BE ON-ON OR OFF-OFF IF THAT'S THE CORRECT BASE. IF ON ON, REVERSE THE PROBES AND IT WILL BE OFF OFF. MANY TESTERS TODAY HAVE A TRANSISTOR CHECKER.
