JOLIDA Issue

So I plugged in my JOLIDA 302BRC yesterday and already It has an issue.
After singing sweetly for two minutes, one of the EL34 tubes imitated the sun and poof, the amp shut down.

Is it possible that one of the bias pots got out of whack during shipment?

Also, according to the manual, there is a stop point for the pots when turned in a counter clock fashion yet I was able to turn two pots several revolutions without reaching the stop point.

Thoughts?

I sure hope it is just a bad tube and not something with the "guts" of the amp. I purchased it from EBay, the outer shell is in mint condition and the seller did a heck of a job with the packing, it was well taken care of.

Thanks for the replies, I'll report back when I install the replacement tube.

Awesome news gents, it was indeed the tube, the new one arrived today, and the amp is purrin along as I type.

A bias check revealed numbers in the 500-550 range and not the recommended 400mv. I dig the easy bias feature and the heavy duty remote control, over all a well built amp.

BTW Mike at JOLIDA is helpful dude.

Happy in Houston.
