I just finished restoring a model 70. The original output transformer was bad. When I removed the tranformer (still riveted to the speaker pan) I found it was filled with PARAFFIN WAX! Not only that, but some of it had obviously melted and leaked out into the tuning capacitor and onto the chassis top. It was VERY difficult to remove. I had to melt it with a heat gun and wipe it off the best I could. Normal solvents seemed not to have any significant affect on the thick wax.

I don't see how anyone could have actually ADDED the wax inside the transformer! It was still riveted to the speaker pan. Has anyone seen this before in another radio? If it was original, why? Moisture?
