Blew the front end of my H4 :(


 

Today I was doing two things at once, and unfortunately transmitted 400W of SSB into my inverted-V while my nanoVNA H4 was still hooked up to my OCFD antenna! Although they are perpendicular, they're not far enough apart to save the front end on the H4 :(

So - how difficult is this to repair? Are the parts expensive, or too small to replace by hand (i.e. should I just buy another)?
Thanks for any helpful hints.
