[Elecraft] K3- Do you think that the front end of my k3 has blown out?

[Eugeni - EA3QP]

I'm guessing that my K3 has been injured during a contest.
The levels that I'm reading in the K3 from the XG3 for -33dbm output 
(the -107dbm  is not audible and -73 dbm has a S-1 in the s-meter) are:

S-meter reading:
160m: 4
80m: 5
40m: 6
20m: 7
15m: 8
10m: 8

How can I fix it or who can help to repair it?.

Thanks in advance
