KPA500 dead again

[Lyn WØLEN]

I have KPA500 s/n 3835 which I purchased along with a KAT500, factory
assembled, last Summer.

 

It soon died and was subsequently returned to Elecraft at the beginning of
August for service, and several parts were replaced.  One part was missing.

 

The unit was received back from Elecraft at the end of August and has worked
flawlessly since that time.  They extended the warranty to cover the initial
defects (thank you, Elecraft!).

 

Today, after operating a few hours, I stepped out of the shack for a couple
hours and returned to find the unit was shut off.  Everything else in the
shack was still on and operating (computers, exciter rig, etc.).  It was
impossible to power on, so I removed the fuse block and checked.  Both fuses
check OK with DMM (I am operating on 115 VAC so fuses are 12a).  There is
power thru the power cable.

 

I can't access any fault information since I cannot power it up.  I don't
seem to have a schematic nor can I find one online to check for other fuses,
etc.  (Anybody have one, or a link?)

 

Suggestions?  If possible I would like to avoid the lengthy shipping /
service delay and $100+ cost of UPS to return it yet again.  Of course I am
hoping it is something that can be field serviced.

 

Elecraft Service has been notified, but it is still early in 6-land.

 

Thanks!

You should call tech to fix get resolved.  Nothing this reflector can do for you.
