Anybody know if/where I might find a fully assembled circuit board for a condenser mic at a reasonable price. It seems like the kind of thing I'd be able to find on amazon for like $5, but I can't seem to find the right search terms. Everything I come up with is for electret elements expecting like 5V power. I don't actually need to polarize an element, but I do need a small amplifier that can power from 48V phantom without exploding and preferably with a balanced output. It is for a DIY project, but I really don't want to DIY the circuit itself. Any hints or help would be appreciated.
