4-channel AM16 clone DIY...
by Chris Randall
If you're looking to get four really nice mic pres for the cost of one, you could do worse than to score this PCB from Prodigy Pro for $100. It has space for four Langevin AM16 clones, and includes a power supply PCB. Aside from the transformers, it's just a few parts, and would be a pretty easy build. (I'd put it midway between "beginner" and "advanced.") The transformers are the expensive part, of course, and you'll need four input traffos and four outputs. Total cost to build is going to be around $1500, using the Sowter reproduction AM16 transformers, when all is said and done. However, when a single channel of AM16 clone goes new for $1100 or so, this is a considerable cost savings.
The thread for discourse on this subject is here. If you were trying to decide what to get me for Christmas, you could just build me one of these.
