[TenTec] Has my OMNI-VII gone bad?

[Bill and Cindy <wb0o@yahoo.com>]

Just turned on my 1 month old OMNI-VII and all the CW sigs on all bands
sound warbly, (like the Cuban stations). No DC hum. Swapped out the power
supplies, no change. Tried different wall plugs, no change. Ground is good.
 
UGH. Of course it only happens after TT service has closed at 5 PM Eastern.
 
HELP!
