Bias all over the place!!!!!!!!!!!!!!!
 
Anyone know why the bias would change daily?

Thinking about putting foil where the fuses go and making a great YouTube video at this point.

I'll call the video "the truth about high end audio".

LOL

Could be a tube or tubes near the end of their useful life

Now both meters peaked and blew the fuses.

CRJCapt 03-01-2019 05:46 PM

Now it won't power up at all even with new fuses.

Vacuum tubes have multiple modes of failure, including shorting inter-electrode style. It may have been the tubes or it may have been something in the biasing circuit. Now that it won't turn on, it will be more difficult to tell if it was simply a bad tube, unless you swap the tubes out and get lucky and everything is resolved. More likely scenario is some other part in the circuit has now failed.

It's been defective from day one. It was made with the bad batch of Jensen caps.

then it had a bias problem.

Then one of the transformers came loose in shipping.

Has always favored the right channel when playing. From day one.

Anyone says something is "High End", I usually bust out laughing.

I see. Sorry to hear about your troubles with the said piece of gear but it happens to the best of them. Shortly after I sold a friend my ARC REF250 monoblocks, a fuse blew. The only had but a hundred hours on them at most. He replaced the fuse which also blew. They were close to $30k a pair. Not exactly a budget piece and certainly high end.

the last trip was six months and it was acting up as soon as I got it back. Probably out of warranty now.

I think I've reached that age where I can't say what I really think because grown people start crying.

CRJCapt 03-01-2019 07:33 PM

I wouldn't mind it IF THE FACTORY WAS CAPABLE OF FIXING IT!!!!!!!!!!!!

But that's just not the case.
