[Milsurplus] I came upon a R390A/URR EAC

[Michael Holdren]

Hi everyone, I’m new to this list. I purchased the other Collins R-390A that Hutch is talking about.

I have a quick question: should there be a burning smell when I power it on?

After inspecting the unit (looking around the insides without removing anything), I realized the radio is actually pretty clean even though it doesn’t really look like it on the top, the bottom is nearly immaculate. So I decided to try using a variac to slowly power up the radio. I went up to about 10v and after only about 5 minutes, I noticed an electronic burning smell. Could this be the reforming of the capacitors, or is it something else/bad?

Thanks,

Michael
