Code 25 output suddenly stops

All Questions

Have enjoyed code 25 for a few years. Suddenly the amp has started to drop output. Happens after a few minutes of playing. All lights on, no noisy pots or anything. Just no output. I can switch it off and back on and output restores. But after a short time, same thing. No output, suddenly cuts out. Nothing. Anyone seen this?

Thank you. New datapoint. Turns out that headphone output works. And if I then unplug headphone, output to speaker works. The power amp board was replaced some time ago because the headphone jack had failed. Jack is part of that board. Have been plugging and unplugging headphones thinking the switch in the jack is the problem - 05 May 2023 at 04:07 PM

See comment. Discovered that the headphone out is working, and when I unplug headphone, main speaker output resumes for some period of time. Eventually cuts out again, but if I plug in headphone, and then unplug, main speaker comes back on.

I have the same problem as you. I bought my amp less than a year ago at guitar center when this happened to me but I did not opt-in to the guitar center warranty for a year so they wouldn't replace it. I played again last week and the amp still does the same thing. I want to return my amp and get an upgrade. It still looks new with all the boxes and plastic that came with it but does not work like new.

FYI, I had the same /similar problem. See my original post. Working fine now. All I did was spray a bit of contact cleaner on a cable jack and insert and remove a number of times and it resumed working. Don't know if that solved the problem or something else. Did seem like the headphone input jack on the Code 25 was the problem

The headphone jack was the initial problem that came in to my mind. But I didnt know what to do. I'll try to do what you did but based on your comment, you said that your power amp board was already replaced? - 04 Jul 2023 at 04:52 PM

Yes. The original headphone jack failed. To repair the tech replaced the power board which included the jack. Amp worked fine afterwards until I started to have the issue of the amp going silent after playing for a few minutes. I discovered that the headphone out continued to work even though main speaker was silent. Since I followed steps above has been working fine. Do not know if that actually worked or something else “ healed itself” but have not had problem since. - 05 Jul 2023 at 12:39 PM
