Test A Direct-Box Transformer?

[smallbearelec]

While Mouser's Xicon 42TMnnn parts are useful, they've gotten way more expensive than they once were. I fished for a Chinese vendor and asked them to clone the 42TM018 10K:10K, since that's the one I have least of in stock. I have gotten my order, compared resistances and inductances and confirmed that they are comparable to those of the Mouser item. If one of the experienced residents is planning to build something that will use this part, pls drop me a message at the smallbearelec address. I will gladly provide samples, as I want a final audit. If these are good, I will slowly ask this manufacturer to clone the other commonly used Xicon transformers.
