    C4 preamplifier dc fluctuation

    Another C-28 S.O.S.

    I thought I had this preamp settled down and it was behaving fairly "rehabilitated" until very recently. I'm fairly certain it's the volume pot. I have another one and installed it and it works "kinda sorta". Very odd things happening with the channel balances. I I think I see ground wires...

    Hegeman Audio HAPI preamp

    Could someone please shed some light on this Stu Hegeman preamp? I assume it differs from the HAPI 1 as this does not have a number? Is it only MM? I haven't found much info after a bit of googling, not even another photo, so any info would help

Anyway, once I hooked it up, I connected...
