Antique Sound Lab Hurricane Problem

I just picked up a used pair of these and was as happy as a clam, because these sound really fabulous.

Until the amp blew a tube (V3) and that socket is now dead. Has anyone experienced this very upsetting behavior from this amp ? Is this a common problem and does it have an easy fix ? Or is the amp just really temperamental and needs lots of tips to the factory ?

The filament lights up, but there is no blue halo and the tube doesn't get hot. Meter reads "1" for that socket irrespective of what tube I use there.

Any help would be greatly appreciated. I love these amps but can't afford to own an amp that is not reliable.

Thanks. I am taking the amp back to the hifi shop where it was on consignment to hopefully fix the blown resistors, if that's all it is. The other amp is fine, and I am falling in love with the sound. This pair has caps modified to Multicaps with silver wiring. It does indeed sound fabulous. I offered $2.5K for them, which seems like a good price for healthy units. I will mention the "cold solder" issue to them.

How can you distinguish old and new versions of the Hurricane?

Apparently, the preferred version has eight .22uf white circular multicap capacitors and the other version has rectangular gray boxy caps labeled "illusion". "My" amp is a mongrel, which started its life with the "illusion" caps and the previous owner had them changed to the top of the line multicaps with silver wiring, blowing over a grand in upgrade costs. I hope that the fix is an easy one.

That's a great question. The older units fail after 3 months and the new units fail after 6.
