K3 No power out

I have enjoyed the wisdom of this group and have learned so much but now it is my time to ask for help. My K3 is showing no power out. I have the K line. The relay clicks when going from 11 to 12 watts. I can set the power up to 110, but when I hit tune I get zere watts shown and verified by my watt meters. Makes no difference of mode, band, dummy load, resonant ant, or multiband hex beam, 80 meter horizontal loop, or 40 meter vertical. There is no output to tune anything.
My last contacts showed no problems. Worked 10 meter cw, 20 and 6 meter ssb ok just two days ago. It seems to be receiving fine. The P3 display is normal, the KAT 500 and KPA 500 change bands with the K3 as they normally do. I have rebooted the K3 several times and have killed the master AC power to everything only to bring it up to the same thing. The ALC, compression, mic gain all register correct, where I always run them. I have checked to make sure the Test button has not been ingaged. Press XMIT and all I get is 0 W. I am sure I have forgotten something simple. Would appreciate any help. Thanks

Re: K3 No power out

"No power to tune anything." Does this mean you've only tried to tune,
and haven't tried actually transmitting cw or phone? If so, and I don't
know how it would have changed, have you checked the Menu-Config-TUN PWR
to see what it is set to? If it is set to .1 it will show 0.0

Re: K3 No power out

Elecraft service set my Tune Pwr to 5.1 watts to prevent ‘inadvertent running of TX gain calibration’.

Have you tried running the TX gain calibration with the K3 Utility?

Re: K3 No power out

In reply to this post by Elecraft mailing list

Don,
Have you tried transmitting at 10 watts, and do you get RF output? Do you
also loose receive when you pass the 12 watt threshold? If you have any of
these symptoms, good chance it’s a PIN T/R malfunction.

My beloved K3 was doing the same thing... one day she was running like a
champ, next day the high power amp up and quite. She is now back at the
mothership being revived. Fortunately, I have another K3 and K3s to put in
line.

Good luck in resuscitating her!
