@northa40 Funny how reading your posts is almost exactly like reading my own LM3886 beginnings. Including the high supply voltage and hum issues. I started out with some of those cheap Chinese "Xy LM3886" boards from eBay. Those are sold in pairs of two complete PCB's for less than the price of a single real LM3886 chip 😉
Should you be interested, my journey up to that point is documented in this thread (or skip the wall of text and check out the pictures): https://www.diyaudio.com/community/threads/neurochrome-lm3886dr-build.295665/post-6517214

I bought one of those XY kits to see what they were about: https://www.diyaudio.com/community/threads/xy-lm3886-kit-review-measurements.294032/
The ICs I received were confirmed fake by TI.

Okay...? I'm not sure what Gemini says as it appears to be speaking in German. I'm also far more interested in having a conversation with a human than with a machine. What are your thoughts on the topic?

I think Gemini is a great help. A useful complement to what people say. Gemini doesn't try to sell me anything; Gemini isn't biased and is good at questioning what people say and what I think.
