Don't know how or when, but I've smoked my TS-590s.    Noticed some odd 
behavior, No ALC showing, no matter how high  the carrier level  (CW), 
or mic gain (SSB) was set.  Power seemed erratic.      Was possible to 
see 100 watts out on cw, but that needed carrier set to around 80, but 
still no alc showing.


I tried a different power supply, different power cable,  reloaded 
firmware and settings,  checked all coax and other connections,  and 
finally rubbed my hand over it chanting" Hom in a, hom in a, hom in a".

Somewhere along the way, I got a whiff of burned component from inside. 
  The "magic smoke" as they say.

Just ordered a 590SG from HRO, year end discount of $1,450.  I'll see 
what damage I can do to this one.
.  I'll pull the voice board out of the corpse and do a transplant. 
Some time in the future I'll send the dear departed out for service/autopsy.

It's just a hobby.  73, Steve KW3A
