Reel deep thoughts...
Well, there are a few of us around these parts that have an M512 or M520. Many of you know I have an M520 that I'm going through and cleaning up.
Many of you have likely read my thread in this forum asking How do you know its time to recap, of which the M520 became a subject. In it dementedchord said:
Many of you may have read some or all of my Tascam M520 Story over in the Analog Only Forum and I inquired therein about potential upgrades to the the M520. At that time Somnium7 said:
Well, here are the schematics. They were scanned at 300dpi from copies. I think there is enough detail to read everything. Apologies in advance for some of the larger sheets which had to span 2 or more pages...the largest scanner bed I had available was 11" x 17". There is, however, sufficient overlap page-to-page for the multiple page diagrams.
Again, with that M520 I have 8 spare input cards and a complete spare master and monitor section, so I've got stuff I can screw up on.
Hoping for some solid advice on conservative upgrades that would likely improve the performance of the board...noise/distortion, etc. Not looking for a lumpy high-lift race cam here, just a good street cam...does that make sense?

as to what chips to use... looks like most of whats in there are 4556's tl072's and such... there are way better chips available but before i would recommend some specifics i'ld want to see an actuall schematic... board layouts and parts lists dont work for me... i need to see what that one is used for... ya dont want to just add say the fastest op-amp available if there's a chance that it's used as say a line driver where current handling is more important than speed... get my drift??? also if/when you change out these op-amps ya should consider adding extra decoupling caps at each opamp...easiest way is to jumper a cap between pins 4+8 on dual opamps...

Well I can attempt a recommendation or two if I had the schematics.
