If the channel that's out follows the tube, I would replace the tube.

Having said that, an intermittent short caused by debris or untrimmed leads may periodically destroy any tube you plug into the SEX if it shorts things out.

In the first photo, it appears that there's a piece of metal between where the blue wire connects and where the striped end of the 1000uF/35V capacitor connects.  If that is the case, you 380V power supply would short to ground through your plate choke, and that will destroy the plate choke.

Got it, the light I used to take the photos was different then where I work, very hard for me to see but I clipped it

One the second photo, there is at least 1cm space between those wires

The dead channel 100% follows the tube now so I have ordered a new one.

Can't thank you enough, cheers!

New tube came yesterday and the SEX sounds great. All voltages are good and beautiful music from headphone out and speakers!

Thanks a ton, Paul!
