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?

Thats why i use tube preamp and ss amp had many tube amps ARC CJ etc to many problems.Now using Pass 350.8 and love it great sound and built like a tank,
If it is a new unit, call Mike at Jolida. They will promptly replace it with a new one. I had a similar problem with their CD player a few years ago. It worked for a day then started skipping on every disc. Mike sent me a new one via FedEx next day and I sent the other one back the next day at no charge to me. First class outfit.
Very possible you could have had a bad tube from the start. Call your dealer (or Jolida if bought used) and let them know what's going on.
Whenever dealing with tube products, the tubes are always first suspect when there is a problem.
Russian tubes are junk, Chinese not much better.
Anybody who thinks they sound good must of never heard an amp with good America, British, German, Hungarian or French tubes.
