    No, they’re likely surface-mount chips.

    isnt that a shame, there is a demo on youtube where a guy compares a dmm xo, a carbon copy and a dm2. the dm2 is so far ahead in every aspect over the other two that it is scary. from the sounds of the xo, i had a suspicion it wasnt using the right chips.

    dunno about the DMM(xo) but the DMB/MB/MT use 3208’s, which are functional equivalents to the old 3008s. wasn’t the DMM(original) a 3005-chip unit?

    looks like a pair of 3005’s in the old version.
    the 4047 is the clock and the NE570 is the compander.

    well it depends what ‘chips’ you are talking about. As far as I’m aware the XO DMM uses surface mount op-amp IC’s and 4x NOS Panasonic MN3008 BB delay IC’s. So everyone is right, the OP just said ‘old style chips’ the XO DMM uses both ‘old style chips’ and ‘surface mount chips’ … surface mount for the op-amps, and old pinned BB delay chips.

    Cryabetes is right that some models had 2x 3005’s that’s because these have double the delay time of the original 3008’s, so you only need two for the same delay time, but it really depends on what you consider an ‘old version’ I think the ones using 2x 3005 were the ’00 re-issues, I’ve never seen an ‘original’ one with those IC’s in.

    anyway it’s all bollocks, use your ears… like the Big Muff there has been loads of different versions of the DMM and they all sound a bit different.

    I presume you are talking about MN3008 BB delay chips, if so I believe they are in the XO DMM. I’ve never actually seen inside one though.
