Re: Crate GX-130C keeps shutting off and turning on
So I took it apart. Checked out some of the solder spots...turns out this amp has a life of about 10 years (check out harmony reviews on this amp and I'm not the only one having this problem). I narrowed it down, to what I thought, was the channel selector button, since this was, as I believe it to be, a simple on/off switch, I took another switch from the same amp and switched them out (one that I didn't use, I think it was the line selector for effects out or something. I don't use it, so I switched it out.)
That ended up not solving the problem. I found out that there is a power line connecting the two circuit boards in this particular amp...it's red with about 10 wires coupled into a 10 wire plug. Took out the plug, sprayed it with contact cleaner, let it dry, put it back in, but it was still acting up, much less than before but still acting up...I jostled the fourth wire (from the front of the amp) and that was indeed the source of the problem. I cut some insulated wire and bound it to this "loose" wire and now there are no problems. Had a gig yesterday and played loud as hell and no hiccups at all.
This symptom is a result of playing loud enough to cause reverberations within the amp, causing that wire mentioned above to become loose.
I am not eletrically savvy, so if anyone knows what this all means, would be more than glad to hear it...whatever I did, or didn't do, it is working now.
I hope this info helps others.
