1 x  ECC82  12 AU7A  RTC PHILIPS   Tube NOS (new old  stock) NIB (new in box)     ECC 82 RTC, Code DGf9, Factory: Heerlen Holland mica-spring,finger-mica, closed getter, Yellow label, long life, high reliability, high tolerance Very versatile name that appears on tubes made in all plants of the Philips company  Philips used a lot of different distribution names for their tubes and these name labels (or a special logo as the bugle boy) do not say anything about a tube's quality. In Canada, in the United States, tubes labeled "Amperex" "Bugle boy", many of these tubes were manufactured at the Heerlen plant in the Netherlands. Germany: "Valvo",  Southern Europe:  "Miniwatt", "Dario", many labels have been used for tubes of different origin, there are millions of"Valvo" from the Netherlands,  and tubes labeled "Philips" from Great Britain where they appeared as "Mullard" ".... So look at the factory codes !! The same ECC with: *Plant, *Year, *a lot, And so naturally of the same: *quality *sound     UNUSED  TESTED at F4: 9,5mA/10,1mA & 2,2mA/2,2mA/v  F3: 10,3mA/9,9mA & 2,2mA/2,2mA/v Typical characteristics are:Va:250v   Ia:10,5mA  S:2,2mA     Measuring emission only is useless toknow the tube's  condition. It's its mutual conductance which indicates its potential life time   Delivered on original box Payment only with Paypal  Colissimo France: 5 €   je décline toute responsabilité en cas de casse durant le transport, les tubes étant fragiles par nature,  La meilleure solution reste l'envoi dans un paquet, plutôt qu'une lettre bulle.
