Tube Folks help me out! I have searched the net and have some idea, but maybe an expert here can help me nail it down.

These say ECC88/6DJ8, RCA Made in Germany with the number 8513.

Would like some help with a positive ID and about how much these are worth. I may Karma them or trade them for a different tube.

Many thanks,
Eric.

    They look Russian to me. Hard to see the getters, but if they are (upside down) saucer shaped they are Russian. Plus almost all Russian signal tubes I've seen/owned have pins that come to a point like that. 8513 is most likely a production date. With 85 being the year and 13 probably being the week. Russian dates usually indicate year and week of the year, they rarely break it down more than that. So 1985 - 13th week of 1985.

    If I was a betting man, I'd say Russian probably from the Reflektor plant.

    Probably worth $5-7 each

    Keep in mind if they are Russian, they never made a ECC88/6DJ8 tube per se. You need to compare the plate and construction to 6N23-P. I cant' make the cryllic symbol that looks like and upside down capital U. 6N23-P is an alternative equivalent, not a direct replacement.

    Looks like these to me, exactly

    P.s. the price on the above auction is a bit high

    I'm going with Brock on this one as the saucer getter is a dead give away. Every Russian tube I have had had had some sort of saucer. Weather it was pressed into a rectangular piece of metal or straight flying saucer shaped.
