Topic: Aerco MP-2 preamp - Part 2

Jerry's last mod to the Aerco was to remove the 9v batteries from the path and go external power only.  I had that done 3-4 years ago.  It's similar to the mod that Doug Oade does for the M148 (Brick).

Wish I would have hung on to my MP-2!

My red 20db gain Aerco is out there somewhere.   I’d like it back…

So I have a question for the guys that still own one of these.  When I purchased mine years ago before I received it the jumpers were removed that provided phantom power.  It's what I wanted because I had/have an akg ck6x JK Labs set up that provided phantom power and I didn't want to smoke that box.  Anyone know how to get the phantom power back operational?  Where would those jumpers be located internally?  I can provide a few pictures of my internals if needed.  Thanks in advance for the help!

**EDIT - Got it figured out.**

^ Maybe you can post some pictures? Those of us that have an Aerco can no longer contact (the always affable) Jerry (R.I.P.) for information...

Would a schematic help? I got one with my aerco years ago.

^ That would be awesome! I always figured that if I had a problem with my Aerco, I could just send it to Mr. Chamkis for some work. A schematic might prove useful, now, if I need to get something fixed. Maybe of interest to some others, also.

Thanks for sharing the information.  Such a great little pre.

That's a schematic for a Universal Audio LA 3A Levelling Amp/Compressor

Not an Aerco MP2

Well shit, it came with my unit and I never questioned it.

Sorry guys!

Damn. Was hoping you had a folder full of schematics and uploaded the wrong one. If anyone knows where to get a schematic it would be great to have a copy in the TS Knowledge Base. I hope to be getting the one I sold in 2019 back in hand sometime soon. I regret selling it but now that Jerry has passed on I'm wondering how I could get it worked on if attention was needed. Caps and other components don't last forever.
