[Amps] 572's

[kingwood]

Greetings to all,

        In my opinion, a "reputable  distributor" doesn't have anything to 
do with the issue.  99% of all new 572B's come from the same factory in 
China.  If the tubes won't meet muster, the problem is in the factory, not 
the distributor.

        Like Carl, I have been buying 572B's, by the case, for years.  They 
all have came from the same wholesaler, in Florida.  I have never had a bad 
tube, even an open filament, until this last batch.  Every single tube 
tested about one half the output compared to earlier purchases. even 30 year 
old Cetron pulls put out more power than the new tubes.

        I sent the entire batch back to the wholesaler.  He said that he had 
no other complaints, at that time, but accepted the tubes back with no 
question.  I have had no other word from him.
