[1000mp] FT 1000MP Mk V Field pre-amp failure

[David G4FTC]

It appears that the mid-band pre-amp on my FT1000MP Mk V Field has failed. I assume the failure was due to lightning although I can't recall having any lightning in this area over the last few days.

I have the service manual and the mid-band pre-amp consists of four FETs Q1019 to Q1022 and I assume it is the FETs which have failed. 

But before I order a new set of FETs, are there any other components associated with the mid-band pre-amp which are likely to have also failed and will need to be replaced? 

Also is the mid-band pre-amp particularly prone to damage/failure?

At the moment I'm running the rig with the IPO button active i.e. the pre-amp bypassed.  

Any advice would be appreciated.
