Hi Rocinante,
I know this is an old thread, but just wanted to say: really nice work on committing to your sentiment in your first post *(i.e. a thread that doesn't die away after a few posts).
This is a really interesting read - great comments and input from all, with an extra gold star for Ian and his guidance!
It's a really good source of detailed and basic information in one hit - the topic's something I'm very interested in (for the time being at least!). Not so much in schematic details, but more-so in a "customising a mixer format to suit your needs" kind of way.
One thing - pictures don't seem to show up anymore. I'd love to see one or two, even if only the outside!...
Best,
Jonny
