Are these output transformers copper primary and silver secondary?
They have Audio Note AN-SPa silver cable coming out of them which is a good sign - my gut feeling is that the darker enamelled wire is copper, and the lighter more orange wire is enamelled silver… but no way to know for sure?
These are great 300b amps, but the output transformers are 8/16 ohms, so I’m either thinking of switching them out for 4/8ohm and/or building speakers which are an easier load!

To get silver sound, you don't necessarily need to have silver windings. At least in my transformer cookbook.
To be sure, you could scrape a small amount of the enamel.
