[ICOM] IC746Pro output power fail

[guenter]

Hello,

Since yesterday my IC746Pro has 50Watt output power on 80m only, going down to 
3Watt on 10m.
Measured with MFJ VersaTuner and Dummy Load
SWR is ok, MIC and Power is MAX, reset did not help
Tested with SSB CW and FM and with both antenna outputs.
MFJ and 746 Power readings are in line.
ALC reading is low as well.

Any ideas, or is a ICOM reapair necessary?

Tnx for help
