Powering and diagnosing the board outside the mixer may be a problem. . I don't have a power supply,or a oscilloscope (although those may end up on a Christmas list......)
I started thinking last night about shotgunning some parts and had some general questions about that:
1. Looking through some threads last night, I noticed you use TI op amps and not less expensive ones (.....honest..... I'm not stalking you Cory..... you just happen to mention 5532 op amps more than others....
). Is there a spec you follow or is this just a brand (or parts house ) preference?
2. Should I socket all op amps?
3. Who is the best small quantity vendor to buy electrical components from in terms of customer service.? The reason I ask this is I noticed some of the amps on my 312b are obsolete (like in the monitor section). If I need some of those I would like to talk to someone about replacements.
I'm getting my shopping list around some caps and some op amps and sockets for now.
One other thing.......
I was looking at putting my replacement input card in and was looking at the mods that were done. Here's the replacement card:
and here's the one I took out of my 312
I looked in the schematics and couldn't find those resistors (?) anywhere. I assume, I'll need to replace those blue ones with ones like were originally like the mixers right?
As always...... Thanks,
Brad
