RCA Mi-9328 preamps

Hi does anyone have the schematic for these preamps, or any information about them? Thanks!

I can't help you with a diagram, but they look like they would be fairly easy to draw your own diagram.

I believe these are similar to RCA BA1A (schematic attached) but don't know that from experience, just an unverified fact stuck in my brain.

Yea I knew it was similar, but not sure how close.

What are the numbers on the bottom of the transformers? If you post good pictures we can figure out a schematic. I've seen these for sale before and been curious. I'd suspect they don't have the same quality of transformers as a ba-1 or ba-2 or they would be highly sought after

I just bought them and they haven't arrived yet, as soon as they do I will post detailed pics. It looks to me though from the pics above to have the same size transformers as the ba1.
