Sylvania elec panel (made by Challenger inside), any concerns with these. Thanks in advance.

Sylvania/Challenger no problem. Sylvania/Zinsco is the problematic panel. . .

I 2nd what the Pope man said

Thanks much. I was gettin’ confused about some Sylvania panels are essentially “Zinsco’s in Sylvania’s clothing.” I get it now. This is the first time I have ever seen a Sylvania in these parts and wanted to double check. This board is a luxury, considering one can spend “way to much time” googling, surfing, etc.
