I wouldn't do that. :-S
Or would I.......?
@RiftAmps I have it on good authority that TAD do not only use Heyboer for transformer production, probably worth asking them when ordering.
now I wish I could find the picture/story again

It doesn't look like a Heyboer to me.
In the second pic you can see the melted insulation or bobbin former that has emerged from the PT. The secondaries are shorted together, but each secondary is not shorted. The primary is ok, and there are no shorts to ground.
The transformer went off to Germany today (at a cost of £20) (sans poo, I've been a bit bunged up and the cat had already been) so we'll see what they say.
No, I have no idea how you complained, but it may have been a bad day there or something was lost in translation along the way.
Not really defending them, most times companies will sort out issues without making a big fuss about it, maybe they are upset about Brexit or something
EDIT: Actually maybe not, not sure. Maybe all of his sun has got to my head

Update:
The PT has arrived back in Germany, and I have had notification that they will examine it and get back to me. Fingers crossed.
In related news, I have just taken in yet another Peavey Classic 30 with a failed mains transformer (a friend of @Rowby1 ). The primary winding on this one is o/c, possibly a thermal fuse as @jpfamps said. I'm tempted to dismantle the old one to check.
I'll also be doing the @ICBM mod (as it's now called!) and change R67 to 1k. It seems like it might be a good idea to add 1k screen grid resistors too.
Well sure enough its the thermal fuse that's the fault. The PT is otherwise in good condition, and given that this particular amp is about 20 years old, it's not done too badly. They do run very hot, and with repeated heating and cooling cycles and vibration, it's entirely possible that this fuse has failed due to age, with no underlying cause.
Markings on the fuse show it's rated at 141 deg C, so I'll get some more with a similar rating and run the amp to see how hot things get. If it's ok, maybe the customer doesn't need a new PT.
I'd go for a lower temperature than 141 degrees though! That's pretty much a last-ditch backup and might be above the melt temperature of some of the plastics.

It really is a very marginally-spec'ed amp. Not impressive, for Peavey.
