Hi Guys, Can someone tell me what is used to coat power supply windings. It appears to look like a dried plastic like glue thats been painted black.
Also, what is the reason for it?
I am asking because some of it has dried out and become brittle on my HRX power supply. Some has chipped off and the windings are bare in a few places. Should I re-coat this with something? If so, what?
Thanks
Ken
