Wondering if it's okay to sand the outside of a transformer or would the metallic dust from sanding cause shorts within the transformer? My fender reverb transformer has this epoxy like gunk on it and I'd like to get rid of that and paint the transformer a solid color.
Thanks.

"The output transformer is a replacement part for a Fender reverb transformer. It is rated for 3.5 W and has an impedance ratio of about 2800:1. Normally this transformer has leads that extend from its back. I didn't like the look of that and changed them to come out of its underside. After rewiring I closed the original holes with filler for automotive repair and sanded the transformer to a smooth finish. Then it was spray painted flat black."
That sure is beautiful.
I've painted transformers for Hi-Fi amps when they're on show. So long as you're careful I can't foresee any problems with your reverb transformer. Make sure its cleaned off well afterwards. if there are any holes I tend to temporarily fill these with cotton wool to stop dust getting inside.

That's a nicely done project. :icon_cool:
Sure, cleaned right up with a dishwashing metal-wool-pad.
Wiped down with alchahol IIRC.
I used Testors black paint, 1 coat covered really nice.
