Hallicrafters T-506 Late Production Set

[M3-SRT8]

[QUOTE=Tom Albrecht;3212247]My experience with a Hallicrafters set that had a problematic coil was as follows:

1. Clean, bake, and coat with fresh varnish: Temporarily fixes the problem, but not long term. (although others have reported better results)

2. Lift the lid by 1/4 inch: not sufficient to help.

3. Add muffin fan and lift the lid: works well. I had a very small muffin fan that fit inside the cage. About 30 mm square, 10 mm or so thick. Didn't like the noise it made.

4. Best fix: replace the coil with a different one (I used a donor from a Teletone junker)

Not all Hallicrafters sets have this problem. You might be lucky and have one of the good ones.[Quote]

Would doing the 1st 2 suggestions help? I mean before I power it up.
