[Amps] 572B's WARNING

[GGLL]

    Regarding Taylor brand, I purchased a year or so ago one Taylor 813 
for a friend's linear and it was labeled as Made in China clearly. 
Dealer was RF Parts and I was aware of tube's origin.
    If your newly acquired 572s have a USA made label (but made in 
China) I think the dealer could be sued in some way, could be?. Those 
are fake USA tubes.
    Last, some years ago my radio master was repairing a Drake TR4 which 
needed new finals, three 6JB6 tubes; we had the chance of a friend 
temporarily living in USA to buy them at a radio shack store.  They came 
in closed boxes but, those were 17JB6 tubes. They were marked 6JB6 in 
the glass, ¿ how?, but coarsely grinding the glass over the 17 and 
writing over a 6.

Best regards
Guillermo - LU8EYW.

>572B's are sold here in Europe by different dealers, the tubes are distributed by Richardson Electronics in England, and they claim that it's Cetron tubes manufactured for National. Sorry to tell, but it isn't the truth - it's newly produced Chinese tubes re-badged by Richardsons as National and also have ''Made in USA'' printed on them. So be careful, before buying. I have been offered, not by Richardsons, but by the distributor to get a full refund if sending the tubes back. Richardsons does not even answer e-mails...

>There are original Cetron NOS 572B's available here in Europe, have a look at   www.clhi-fi.it   It's in Italian, but click on ''Surplus'' and than ''avanti'' to go to page four. There are no prices on the WEB, but in an e-mail they asked 500 ''euros'' for a matched pair, plus postage. That's totally USD 645 for a matched pair!!!   I know that there are also NOS Cetron 572B's available in USA, but unfortunately we have to pay more postage, customs, 25 percent VAT etc. so here we always try to buy from a European Community country, this was no customs and other extra charges to pay.
