I cannot find anything wrong with it now.

It does/doesn't work?

Anyone familiar with these amps.?
I'm surprised the Cockroft Walton pump cirrcuit is enough to power the HT
of
the ECC83.

Not a pump, a full wave bridge.

As Homey says, look again. Although it's peculiarly drawn, it is just a
simple full wave bridge, with 250v AC input. The caps are just spike
bypassers to protect the diodes. As to why it cut out, it may be that
something locked out that complex soft-start circuit. Give Trace Idiot a
call and just ask. I've found them pretty helpful in the past ...
