The $5 preamp Urban Legend

It's pretty incredible that some people do manage to build a servicable
preamp with all those things; connectors, box, power supply, switches and
other miscellaneous components for more like $50 than $500. I'm specifically
thinking of the Rolls MP13.
Sure - no transformers (or worse, crummy transformers), wall
wart power, and most important, mass production. You can buy
a preamp-sized case with no holes in it for $10-15 and hack
it out, but if you make a drawing and send it to a sheet
metal shop for punching (for neat, round holes exactly where
you want them) it'll cost $50 just for that. The
manufacturer who turns out $50 preamps by the thousands gets
the same case made in China for about a dollar.
