Ok, so I've got this Neve mic pre clone that I'm working on. The board is my own design, but is pretty much a BA283. The transformers are the Sowter versions of the input and output.
Anyway, when I'm on a reasonably high gain, I can hear the test tone coming from the preamp! It seems that I am hearing the output transformer. Is this normal??? The preamp is not connected to anything else that would produce sound. Just a sig gen and a scope. Any ideas??
