Many of my sets working with all or 80% of the original capacitors.

However, this is the adventure of today... The vertical is open at 90%, so I decide to connect a DVD and a VHF modulator... Weeee, a picture!!

Suddendly, the EHT expired
After 2 second the flyback starting to frying

Immediatly I cut off the power.
I can't tell you my thoughts in that moments

I have checked 2 capacitor connected at cathode of the damper and at the cathode of the horizontal output tube (all good). Also I checked the cathode resistor of this tube, results 60 ohm instead 33...

During the last startup of my Westy I seeing a little lightning in the 6W4. That tube is italian, made by Fivre

I replaced for testing with a 6AX4, and now I have EHT. My flyback (and my heart) are saved

I have a question: what is the good level of cathode current for my set?
