K3 no power output

I just received a "new to me" K3. It is a recent serial number 18XX.
The receiver works fine but there is no output power. It goes into transmit the transmit light illuminates. but no power at all in any mode or on any band nada, nil, zero!!! I have checked all the obvious things.
I took the covers off and could see nothing that looked wrong. Anyone have any ideas?

Also, I have a second K3 that I have been using as my primary radio for 3 months. When I moved it to test the new k3 I heard something rattling around. I removed the top cover, turned it over and out fell a wound torroid. I can's see where it is missing? It is green colored with just a few windings.

Both of these K3s were factory assembled and tested!!!
Needless to say I am having a very bad day!!

Make sure CONFIG: TX INH is OFF. Either Hi or Lo will prevent transmi if the TX INH pin on
the accessory socket is not connected.

If you connect a paddle, do get a sidetone when you key it?

If you are trying to transmit SSB, are you sure the correct mic connector and bias setting
is selected?

Re: K3 no power output

Vic,

The TX INH is set to off. Yes, I do get a sidetone and the first bar of the RF meter scale is also set.
There is no power indication on my external digital wattmeter. I also had another ham less than 1 mile away listen, nothing heard.

Make sure that you are not in "test mode". Is the TX panel indicator
flashing? If so press and hold TEST to turn it off.
