Well that's what my Rotel amp is doing out of one of the six channels. Having stripped it down the power switch fell off it's PCB, and the channel crackling was the one closest to the power switch. Here's hoping that's an easy fix, although I think a good general service is in order having gone to all this effort so far.
Why is this relevant? Well it will power my home built speakers which are now up and running (or were up and running until the amp gave up). The current active crossovers are a couple of 2x4 MiniDSP units. Now these are nice units, easy and simple to use and the Analog Devices chips inside always sound good anyway, but I feel the system is lacking a box full of OHDSP boards in their place.
The box is almost ready, just waiting for these ADC boards that have been on hold for a while. A Farnell order is due with many parts for many projects so I will finally get the resistors I am missing, and I will finally have somewhere I can work on these more sensibly than before. Now I just need to sort through the mess of "neatly" packed electronics I did when I moved...
Stay tuned for more to come!
