I need Solid State help
How technically savvy are you? *Solid state boards can be harder to work with because many new chips are soldered directly to the board, whereas tubes can be "easily" pulled from their sockets. *I had a problem with my old Crate because the distortion channel stopped working. *After some snooping with an oscilloscope, I discovered that the 1458 op-amp was blown in the pre-amp ckt. *I unsoldered it, and replaced it with a socket, then plugged a Radio Shack 8-pin IC in... presto! *It works!
If you don't find any of the obvious problems (loose wires, cold solder joints, burnt components), you're probably looking at a dead IC somewhere. *-Andy
