FS/FT: SCA Built Preamps C84, A12, T15

[jdier]

I am interested in turning my SCA rack 100% N72 so I am looking to trade out or sell off my other SCA Preamps. Here is the history of each (you can also see much of my communication with Tim on the boards here):

T15 (not sure of rev) - Purchased assembled. Told that it was built by SCA, but does not have the sticker. Looks beautifully built and has never had any issues for me. Great build.

T15 Shipped and Paypalled - $135

C84 (rev 1.91)- Purchased as a non functioning unit from someone who had also purchased as a non functioning unit. I went through the entire BOM and verified all correct population of parts and then ran all testing SCA suggests and everything checked out OK but still did not work. Found a simple broken trace and installed a jumper, balanced the in and out opamp voltage and everything works perfect now. The soldering is not beautiful, but there were no bridges and everything works fine.

C84 Shipped and paypalled - $245

A12 (rev 1.4)- Purchased as a partially assembled from someone who gave up and lost hope. Their work was actually beautiful and I finished the build in about 45 minutes and it works perfect. The original owner made one small error that is worth noting and could be a deal killer for some... He did not mount the surface mount sockets for the SCA25 Opamp, instead he just soldered it right to the board. This would only be a problem if you had a desire to swap out opamps on a regular basis. You could desolder this one, but I did not see a need to mess with it as it was all working great.

A12 Shipped and Paypalled - $365

I have bought and shipped about 5 SCA boards and know how to pack them correctly. I would feel best selling them to someone who has worked on them in the past and feels comfortable with troubleshooting, but I will sell to anyone interested.

I would also entertain trades like this:

A12 for N72
C84+T15 for N72

I would also consider partial trades for unassembled kits or partially assembled kits.

I am NOT interested in any of the other modules from SCA at this time.

Thanks in advance.
