This auction is for one new old stock Telefunken ECC83 / 12AX7 smooth plate twin triode in original box as shown. All have the diamond pressed in the bottom between the pins, and all have good, clear printing. The third and fourth pictures show all five available pieces. All have the same Berlin factory date code. All were tested on our Hickok 539C with results of between 1800 and 2100 for all of the triode sections, where 1700 is 100% of the expected new value.

Due to too many requests by overseas customers, I have to state in the USA it is illegal to falsify the value on Customs forms, as well as being against eBay rules. Do not buy this item and then ask us to falsify the forms. We always declare the sales price, as required by law. If you have asked any seller to falsify the forms in the past, ask yourself this question... Why would you want to buy from a company that demonstrates it is dishonest?
