Subject: [Elecraft-K3] 8.215 trap and C10 on KAT3
 
I have found many references to removing this trap so I believe this is what I need to do. I wanted to confirm in practical terms before I start cutting out components.

I have two K3s. One is an older unit I bought from a friend's estate and it indeed had a KAT3 in it. After smoke poured from the tuner section, I discovered two burned caps on the underside of the board. I also noticed the core must have heated up enough as the insulated terminal to one tab of the circuit breaker was burned a bit (most likely where it was touching the coil).

So to confirm, the now charred caps can be removed as well as the wound core L10 from the top side of the board. I should unsolder that and place a jumper to the two points where it attached to the board.I can also cut it out and clean the ends of the enameled wire and bridge those I read.

I put a picture on my website: https://user.xmission.com/~toms/KATTRAP.jpg

The core in question (L10) is the blue one.

Thanks,

Tom NY4I

Hi Jim,
Thank you.
I think many of us have already completed this form some months ago ...... other than a comment on their website saying Elecraft would be in contact  early in 2021 ... nothing heard.

Tomorrow starts week #6 for my RSA to repair a KIO3B board.  I am a dedicated long term Elecraft customer and wonder if others are experiencing this same length of time for repairs.

Re: RSA speed

Yup - They are running about a month behind on K3 Repairs.
I just got my K3 back last week. I should get my KPA1500 back next week.
I suspect they are also behind on board repairs.
