My drip 670 V3 is melting the wax out
The sowter transformers and it covers the whole pcb it was angled in the rack so it’s across all the tube sockets all piling up at some HV connections…

Now it’s shorting hv somewhere when the unit is on operating temps and I switch it. Off and on again. I suspect a inrush current shorting somewhere by all of that wax everywhere touching 240/440v is that even possible ?
My 2nd rectifier tube (5ar4) has died

How do other cool this design? Or is it just a bad design and do I need to get those transformers away from the tubes?
Or is forced cooling the way to go?
 
If you've had 2 rectifiers die it would suggest there's a short somewhere, creating the excess heat.
