    There is now a final BOM available via the link.

    This is just a change of part number for Capacitor C131.231. Values are unaffected.

    There will be no further alterations unless parts become obsolete.

    Good news!

    Up and running! Thanks to Al for getting it going as I'm still unable to physically do anything.

    Bad news!

    The EQ is off but we ran out of time. We will have to sit down and figure it out when I'm better.

    Hi Andy,

    I have but I want to sort the EQ out before I get the front engraved. My OCD can't accept the fact it's not right.

    Everything fitted really nicely and there's no hum at all. I'll post some internal pics when I can.

    I'm really pleased with the size of the casework. It'll fit perfectly.

    So I am not even one fully finished unit into this venture but.........

    The Bigbottle MM/MC switchable phonostage is in development!

    After being asked numerous times about a MM version, I decided that we would provide one.

    Same circuit as the current MC version but with a few changes to the front end to get the MM capability.

    This is some way off yet but just thought I'd share.
