[R-390] Hot Chassis

[Stan Gammons]

Hi All,

After swapping all of the paper caps, the plug in electrolytics, 
replacing a couple of tubes in the audio deck which were causing an odd 
motorboating in the audio, replacing the RF deck and performing the 
alignment; I have a pretty decent performing R-390A now. There aren't a 
large number of out of tolerance carbon comp resistors in the radio, but 
at some point I plan to go back and replace them one deck at a time 
until all have been swapped. But, I don't really like being shocked and 
was wondering what is the preferred method to get rid of the hot 
chassis?   Simply install a 3 wire power cord?  Seems like I read 
there's still enough leakage current to trip the GFCI breakers, so maybe 
that's not the best way to go about it.
