Now to restuff those old caps. I clean out the little metal box, stuffed 4 new 0.033 uF caps inside and filled it with wax. A power resistor gave out and I had to use a modern looking one.
That left the big filter cap. Sparton mounted it by punching a hole in the chassis with bent over flaps and shoved the soft aluminum can in. I've had to deal with this once before. They are a bitch to get out.
Finally I managed it and was treated to a nice label which had been hidden before - 16 whole microfarads
Now, I can cut off the bottom and restuff it.
I used a little JB Weld to reseal the can.
That leaves the scratchy volume control. I carefully unsoldered it and popped it open. I was quite surprised at what I found inside. That is one sweet potentiometer
I used a little deoxit and no more scratchies.
