analog for the people!
So as the story goes, we've got a PM1000 that started out life as a 32ch console which my studiomate bought, sold half the strips and the frame, and loaded the other half plus the master section and supply into a 16ch "sidecar."
He then re-capped the whole thing with Panasonics and modified the EQs for better semi-parametric mid centers...and wired it so that all channels are summed to the masters, plus channels 1-12 are direct out, while the last four are only summed to the masters.
He put one cap in the each of the four masters in backwards so they blew when he powered up...and then gave up on it and left it sit for five years. I got sick of it collecting dust so recently i replaced those four caps (right way around this time ) but the masters are still out...
I haven't worked on a PM1000 before; the circuits are pretty simple but I would appreciate some pointers on where to look/test with these modules...the 12 direct channels work fine as direct preamps, in fact I tracked through several of them at a session yesterday....but I'd really, really like to get the masters going so I can submix with this board as well as mix down with it...I can confirm that the masters as well as chs 13-16 are getting power, but otherwise I can't get any signal through them except for a very, VERY faint signal through Master-1 by cranking it through another gain stage in another console...any suggestions on where to start in getting the masters back in action knowing that it did have one cap in each module blow?
Haven't got an original service manual as such, but I've got some schematic printouts of mediocre quality, they're hard to read!
