    I got NOS RCA 6DJ8's from Antique Electronic Supply quite inexpensively.
    From Audio Asylum, Joe's Tube Lore:

    "RCA never made 6DJ8 family tubes. If it’s an RCA and has a ridged top it’s either an Amperex or a Siemens. I’d watch this brand closely if you stumble on it. Many tube dealers will sell lowly RCA 6DJ8 family tubes for $15 to $20 a tube without realizing that there is European made gold inside. Check the tube’s top for ridges, the label for where it was manufactured and if everything checks out, buy it! This is one of the absolute bargain brands in this tube type."

    I bought a sleeve of "RCA 7230" 6DJ8/ECC88 a few months ago ($12 a tube) and I'm confident they are Amperex. Other than gold pins, they are also indistinguishable in internal construction from my 1965 Amperex USN-CEP 7308's and 1966 Amperex 7DJ8's. The 7308's and 7DJ8's best the "RCA" tubes slightly with a more musical bass. Other than that, I can hear no differences. YMMV.
