    Re: 4004 can't find a 45?

    Rapidroy:

    I bumped up to silver membership and still no schematic?

    As I said earlier, look in the 4002 manuals. One of them (can't remember which) contains the 4004 and the scan quality is also much better than the excerpt you posted earlier.

    Well appreciated Yes -  thumbs up

    All is grand in Beoland! I pulled TR5 to test, it tested good, put it back. Put the belt and platter back on, put a 45 on just for fun, pushed start and the tonearm went right by the 33 part, it did the auto switch speed to 45 and dropped on the 45 record!!!! My guess, cold solder joint?

    Very cool, Roy.  Way to keep at it, and thanks for supporting the site by upgrading to silver.

    Current primary listening:  SMMC20EN -> BG4002 -> BM4000 -> Beovox M70

    Quite possible - apart from obviously broken components, bad caps and bad solders probably cause the most problems with old B&O kit. Bad solders are more common in TVs because of thermal stress but you often see them elsewhere too. Wave soldering wasn't that advanced back then, and occasionally you see a problem that was hand made in Denmark Big Smile

    Hope you can now enjoy the deck for a long time Yes -  thumbs up
