I just picked up a 2019 Warm Audio WA87 mic that had a Tab T13 transformer mod by Zen Pro Audio. The original Cinemag transformer was included with the purchase. Right out of the gate, I noticed that the output level was much lower than expected. My mind immediately flashed to something I read here about a large batch of the Tab Funkenwork transformers that went out with wrong wiring instructions. I also noticed that this mic has a static pop that occurs periodically. It's intermittent. Sometimes 30 seconds apart. Other times 8 minutes or more apart. I don't know if these issues are related or not, but I'm beginning to think so. Before I return this mic for a refund (I'd rather not because it was a good deal and in all other respects, I'm liking it), can you tell me by looking at this photo which wires need to be switched to correct the output issue that I'm having?
