I read with interest the introduction of the BC-2B mic preamp kit. It turns out that I have a pair of these original (two-channel) RCA preamplifiers, and a handful of extra transformers. The transformers are definitely made by UTC, but they're also definitely not LS-10s and LS-27s, in spite of what it says on Larry Seyer's website. I was curious, Kevin, if you've done any research on the actual transformers in these preamps. I don't remember if I asked this once before, but I've been trying to decide if they're worth anything for a hi-fi project.
