My sister bought a mixer here a couple months ago for about 80$. She needed it to record some hot sitar action in India. She sends me an email saying that either she forgot the ac power supply or it wasn't in the box or lawn gnomes stole it to use it in devil worshiping, but she doesn't have it. She tried something over there with the equivalent voltage/amp and the mixer got super hot super fast. I call up guitar center where we got the mixer and they don't have that exact power supply. I call up yamaha and get connected to the parts department and guess what, the power supply is 60$. I made sure she was talking about the power supply, not the model itself. Are those things really that expensive? Guess so. Bastages.
