    This was going to be a thread about a Heathkit RF Signal Generator left in my garage by the previous owner. Is it useful, that sort of thing. Being an unapologetic tinkerer, I had to open it up. And looking up at me are the words....IEC Mullard! Woo hoo. One 12AT7 and a 6AN8A.

    GT BRITAIN
    IEC Mullard (Next to each other, not on top of each other)

    1022-940
    VF3
    88K4 or 58K4 or B8K4 Cant quite make out the first character.

    Anyone know a good reference site for Mullard dating, etc.?

    Thanks!

    This happened to me . . . several times in fact

    Most recently with some old cinema amp and two very fine Made In USA el84s

    I have also scored two blackplate RCA 6l6s, RCA and Sylvania 6v6s, numerous rectifier tubes and whole slews of 12au7s and some good Mullard and RCA 12ax7s
    . . . also a bunch of numbered tubes I have no idea what they are or do from old electronics bought at garage sales and estates sales.

    Ha, I did, and it returned one hit, an old TGP thread on which you tell the guy to google on "Philips tube production codes" :)

    http://www.thegearpage.net/board/showthread.php?t=382932

    But then I googled it with two LL's, Phillips, and it returned a number of options. I'll do some reading. Thanks. :)

    When I first started working for a communications company I found out they had just cleaned their attic a few months before I started. Tons of tubes and tube testers in the garbage. Luckily when I started working at my current job, I found hundreds of tubes. Some of them are nice (12ax7,12at7,12au7). Some I have no idea. Its neat finding stuff like that.

    I was on a Univox amp binge for a while and found most of them are loaded with Mullards. Old home organs are a great place to find tubes and spks. They are at thrift stores around here for about 20 bucks.

    Very very cool.

    I have had a few similar finds. I was given an old Viking recorder and was getting ready to deep six the thing but thought I should pull the tubes.

    4 - Telefunken diamond bottom 12AX7's
    2 - Telefunken 12AU7's

    Made my day.

    For the old 4 pinners listed above, drag out that old Atwater-Kent radio. Should fit right in :).
