Default Sender Resistance Testing

Earlier this evening, I finally found the last component I needed to investigate related to the abnormal test results I was getting for the V1J Speech Amp circuits in the Sender.

The component was resistor R49A, related to the V1J Plate Load and I had to remove the T2A Transformer, once again, from the rear skirt of the Sender chassis to reveal its location. I had suspected it was hiding back there at the very start of this quest, and had actually looked with a small, flexible mirror behind T2A, to no avail, so I went on to track down all the ‘easy’ stuff first. More on that later.

In any event, to save anyone else hunting for this resistor down the road, here is a photo of what it looks like and where it hides. It is rated at 100 KOhms, with a +/- 20% tolerance at 1/2-Watt. This one tests out at 126.4 KOhms, so is now on my “To Be Replaced” List.
