Mike,

Sorry to hear this.  I know this is your "dream" radio, but some dreams 
turn into nightmares.   As with your tuner problem, only you can decide 
when enough is enough and when to stop throwing money at a particular 
piece of gear.

I'm sure even the new radios have a percentage  of failures, but I think 
it is a small percentage.

The 590's from this list that have gone back for service recently have 
been for a free out of warranty mod.   This mod was begun  at the 
factory starting with Jan 2014 production.   Only cost to those of us 
who sent in the radio for the mod was one way shipping.   The mod and 
return shipping was done at Kenwood's expense.

The only other "real" problem I can recall was  some low value fuse in 
the  antenna  line.  For a short time in early production (2010)  a 350 
ma fuse was used, later replaced by a 500 ma fuse.


Our late friend from this list K7RX (SK) had 2 fuses fail, one being 
pilot error.   He had 2 stations connected to  his antenna system using 
a 2 position switch that didn't have enough isolation  to protect the 
590 from the  600 watts of the other rig/amp.


Good luck on this, I know it's aggravating,
Steve KW3A
