[Elecraft] K3 HI RFI burnout

[K9FD]

I have had a tech ticket in with Elecraft for a few days and have had no 
reply,
thats another story and not addressed in this posting..

I was sitting here at the op desk last week and listening to aM 
broadcast band
on one of my K3 and suddenly the HI RFI was on the VFO B display, it was 
still
receiving fine,  but checking it has no RF out,  and will not shut down 
with the
power button.   I checked the manual and understand why the error came 
on and what
the solution is,  but see nothing as to what the problem can be, what 
burned out
etc.   I checked on line and see almost nothing on the subject, just the 
normal
off topic replies to the question.

Has anyone had this problem and repaired it themselves?  I saw one 
posting that
it was the BAR64-05 burned out.   I looked visually and it looks ok,  
but not sure
if it can be checked in circuit and what the readings should be.
Looking for help,  perhaps Elecraft will come through this week? Like to 
order parts
if necessary and get the radio back in service.
Appreciate any help, thanks  73  Merv K9FD
