Hello all.
I have a US Audio Mix-8 Line Mixer, rack mountable. I changed the fuse and powered on with a current limiter (lightbulb thingy).
I noticed that the voltage regulators (could be 7818-7918 - not sure because the heatsinks covers them) get hot, even though I'm not connecting lines in nor speakers. They get up to 52ºC in a couple of minutes after powering on.
My question: is this normal? My gut tells me it isn't, and I'm thinking about some faulty component pulling too much current. But I have investigated and can't find nothing.
Thanks in advance for any help in this.
