Collins 75-A4. Receiver repair.
Here's a case where insufficient test instrument abilities made a simple repair harder than it needed to be.
I initially used an insufficient tube tester as My Hickok tester was waiting for a fuse.
That cost Me unnecessary troubleshooting to effect a simple repair.

I've recently purchased a 75A-4 and it had tube issues as sure does preform for the video....

Great video! It was very informative; especially seeing the Hickok tube tester being able to detect the problem. Hope to see more of your videos. 73 es 88

Phew! That was easy. It's almost NEVER the tube! Ha. Very nice 752.
