KPA500 problems

VK7JB

Wow Mike, that's really bad luck and very frustrating.

I've been about to order a KPA500 to go with my K3, but after your story, I
might hang back a while.  Bad news about having to ship your amp back, but not
as expensive has having to ship it back to the US from down here.  I wouldn't
like to have to face that cost.  But what puts me off the most is that there are
 "mods/upgrades" being done  to serial # 26.  I might wait a while before
hitting the order button.

Hope all gets sorted out for you Mike.  As someone else said,  at least you're
dealing with Elecraft and you can be sure it WILL be sorted out in a timely manner.

73,

John

Re: KPA500 problems

Thanks for the suggestions Ron.
>First, what size fuses did you put in? There are two different ratings

>supplied: 6A for 240 volt mains and 12A for 120 volt mains.
The fuses were the 12A ones (I still have the 6A ones in their unopened
envelope.)

>Before you turn on the unit with the new fuses, check the transformer tap

>setting as described in the Owner's manual under "Installation".
I checked the tap is yellow as it should be. The measued AC is 120V. I will
go to the store this morning a buy a few more fuses
and give it another try. The fuse holder looks good. It is positioned so
115V appears through the fuse window, and it looks like the
contacts are aligned correctly to mate with the top two and bottom two clips
on the inside of the fuse holder. (If it were placed in the 230V
position the contacts would mate with the upper one, middle two and bottom
one clips.)
Other than defective fuses, I can't understand why they would blow. Hmmmmmm.
Wayne did contact me and I am sure we will get this all sorted out. Still
the best products from the best company in my book. Just
a spot of bad luck for me. You can check out my station picture on QRZ.com
and see my K-line in place on my limited desktop.
