Bij de buis op deze foto mis ik daarentegen de vergulde steekpennetjes van de voet.

Volgens deze bron hoeft dat niet altijd zo te zijn:

ECC803S, E83CC, E803CC, 6L13: This is a premium European version of the ECC83. The "S" indicates Special, and these tubes were screened for low noise and matching internal triode elements. These are rare in the USA. Telefunken and Siemens are the brands most often spotted, although several of the Mullard factories made these for various labels. Most of the Telefunken and Siemens tubes had gold plated pins. BEWARE: I have seen smoothplate Telefunken ECC83 tubes on auction sites with aftermarket gold plated pins, being passed off as NOS ECC803S tubes!! The ECC803S is a frame grid tube, and it's inside construction is different from a smoothplate. The ECC83 smoothplate or ribbed plate Telefunken tubes NEVER had gold pins! Be careful, and get a solid return policy like ours whenever you buy costly tubes like these. Sometimes the E83CC also carried the 12AX7WA military type label, even though it is a European made tube. The build quality and performance of these tubes are similar to the Mullard 10M type listed above, although the sonics will differ between German, Dutch, and British tubes. The 6L13 is rarely seen, and then usually only in a Mullard made longplate, but these are well worth the high price they command. They were made for other brands as well but all have the 6L13 on the label.
