A Hallicrafters S38-C recap - part 3: Layout considerations.
The original capacitor for this unit was a multi-unit paper tube, and I’m not going to dig the potting out of it to see if I can fit new parts inside. That’s just not going to work, and I don’t care about “looking original.” I decided to use the time-tested method of some solder lug strips and discrete capacitors.
After removing the other one I put in there (and made a mistake with) I settled on these 5 lug strips - one for each capacitor. Since the chassis is hot, I ignored the center terminal and grounded the 4 outer terminals on the back lug. The front lug will be the actual connection points to the individual capacitors.
The only real consideration here is where to place the parts. I thought about doing it this way first:
but the two big 47s push on one another. I decided this:
was probably better, as the circuit doesn’t care about where they are, just that they are electrically connected to the right point. It gives everything plenty of space.
Next step is to form and solder, then run the connection wires. Still waiting on that blue wire!
