    Anyone know where I can get the peanut lamp (5V 60mA) used in the < > photocell control module in the keyboard.  Its B&O part number is 8230069.

    Thanks

    Hi Martin,

    A few pix of the mystery cartridge.  Here fitted to SME on old Thorens.  Then I found the arm needs fixing!  So cartridge is still unused.

    In the mean time I’m concentrating on refurbishing a rusty old GR8002 with broken MMC1 from eBay.

    Thanks, martin.  But I need to buy some gloves first, because NOTHING gets the awful stuff off your skin!

    Sorry for delay in answering, Martin!  Thanks for the leads.

    Checked all voltages including 14a around Dolby board.  All present.  But worst possible result for fault – after reassembly it works perfectly!!  Tested now with many tapes both in playback and record.

    Guess I just wait for something to show up some day … sigh

    Thanks,  this deep electronics is daunting for an old bloke!   But B&O have made any servicing a delight!

    I will check voltages around the Dolby ICs.

    And your suggestion of Vref will be done, too.

    Thanks, TJames for your reply.  Yes, opened and replaced a number of darlingtons in circuit around RL101.  No VU’s on recorded tape.  No change on micro pin 36 !REC.

    Thanks, Dillen.

    From the circuit I thought RL101 needs to pick for play.  No, nil display on VU’s when recorded  tape running.
