Wish I had read this thread a few months back. A couple of weeks ago, I was having a problem with my left mono block tube amp...no sound. So, I switched in my ss tube stereo amp ( which I run off my second output from my preamp). I had switched off my tube amps and had made the speaker cable change and the ic cable change while all amps were off. Nonetheless, I figured why not take a look at the ic's to the tube mono block amps ( which were off)...this while the ss amp was playing. NOT a good idea at all!
The crackle through the speakers was pretty scary! Luckily, no damage done, but a lesson learned. Best to have ALL gear off when changing cables.
