Brought myself to doing that.
So far re-stuffing the caps was a walk in the park. Did all backelites and, today, the tin-can ones - they were not potted.
Now this big one next to the power XFMR, seems to be a challenge.
I desoldered it, drilled out the rivets, cut the wires and the panel came off relatively easy - just had to be careful not to crack it.
But then it's all potted with tar, and, unlike in the small backelite ones, it's a large can and the same technique is not likely to work.
I removed the tar at the bottom, to the level where caps are, but what to do next?
Short of using a chisel and a hammer, does any one of you know any quick (or quicker) and not too painful way of cleaning this can up?
And, when the cleaning is done - how do I secure the panel back? The rivets seemed to be glued right in the tar, so now that the tar is gone, what do I rivet it to?
The caps probably will be soldered right to the panel, but securing the whole thing in the can does not look straightforward.
