Whaddya think, folks -- should I replace this width control?
Talk about burned up. While looking around, I had noticed a terminal on that control where something
used to be connected. I'm pointing to it in this photo.
The lead formerly connected to the bare terminal is marked with a yellow arrow. That's not the only horseplay I've found this set. Notice the flat black cap connected to nothing (also marked with an arrow). So far, I've found two disconnected caps.
I guess when the control burned up, the guy just moved that lead to join it with the power tranny lead, taking the pot out of the circuit.
Who knows, the width might have been acceptable at that stage, so maybe the caveman "repair" was just being thrifty.
I'll replace it anyhow, although the price for a 200-ohm/4W rheostat at Allied Electric made me swoon ($75).
Next step: looking for evidence of what burned up the pot in the first place!
