Thanks Gus I hadn’t seen that! I can certainly say that his issue was not my own however. I checked all that over and over, and what’s more, I never had any issues at all with hum or buzz. Clean mic just way too quiet. Unplugging the mic from the pre I realized that all the noise I was hearing was coming from the preamp I had cranked. Not even hearing the noise from the mic itself. This was all after troubles with a bad batch of tubes, so I was pretty much at wits end. I take my time and give all my attention I’ve never had a build just totally not work right from the start. I suppose I was due...

Have you read this?

Shouldn't be this complicated to provide clear wiring diagrams for transformers...

Or just make wires the same colour as originals: clients can look at vintage mic schematics, follow the colours, and never have a problem.

Neumann always marks them: sw=black, rt=red, bl=blue, gn=green, ge=yellow, bn=brown

Banzai: The AMI T49 is a PCB mounted transformer. There are no coloured wires.
The terminals are labelled A, B, C and D.  A and B are (should be) the the primary, C and D the secondary.
The transformer board in poctops PCB kit has the same labels, so it's very hard to get it wrong. If the labels on the trafo is right.
