Radiotrope capacitor box.......its not tar filled....white stuff?!
6/5/2003 6:13:06 PMSEAN
Hello, I have opened the capacitor box and its not tar, its white stuff about 1/8 inch thick with metal under neath separated by what looks to be cardboard like a battery. At one end of it at the top was a 16uf 450volt cap that had corroded a long time age.(this one will be replaced for sure!) I would think all of these wires are soldered to a cap that is tied to the case for ground. Did they just stick those match box caps in here that I am used to seeing under chassis of 30's radios? I am wondering how to remove these as they are not covered in tar. I can chip away the wax?, but then what? The power supply must not be exactly like a us 80 because that schematic didnt have a 16uf cap.

Hello, just thought I would add that the box I thought originally had the caps in it turned out to have the inductors in it, so all that work just to find out no caps....well at least I know where the inductors are now!

Hello, just a note..there are what appears to be about 5 different caps here divided by these thin cardboard insulators

Hello, I am not sure these caps are tied to the case. When I measure to the case I get .595nano farads on all of the wires. When I measure each cap from the black/yellow trail wire, then I get 3.5ufgreen wire, .78uf blue wire, 1.869uf red wire, .875uf black wire. Also the 16uf cap did not have a cloth wire attached to it, it had a rubber wire so I would think it was added later?

Hello, If this 16 uf cap was added later then they had a tough time digging out some of the old cap to fit this one in because it looks like thats what they did. Question is if I start digging these caps out, are they oil filled or or filled with something else. I did notice something leaking out from the bottom of the case. It seemed like a brown stickey oil.

Hello, also a note.....is any of this material hazerdous to my health?...This thing smells really wierd. Not a bad wierd, but strange

Hello, dont think I have a choice here so I am drilling out one of the caps so I can have a spot to hide the new ones. Just hope this stuff is not hazerdous material.

Hi Sean,
The white stuff you described could be asbestos. You may want to wet it down with water before trying to remove any of it. This way, it won't scatter. As an extra precaution, you may want to wear a mask.

I found a small sheet of asbestos in my 1950 Stewart-Warner 9151A about 2 x 3 inches above the dial lamp. I went so far as to contact the Ohio EPA about removal and disposal. I was told that the size of the asbestos wasn't enough to cause harm. I wasn't successful in removing it after wetting it down, so I just left well enough alone.

Good luck,
Mark

Sean, yes, it's most likely asbestos. For situations where you feel you want to remove it, but need something for a heat blocker, you can buy some "safe" modern substitute sheeting at a heating/plumbing supply place.
