Hi everyone, I’m having an issue with my Trinity TC-15 where the volume suddenly drops after about 15–20 minutes of playing and I start hearing crackling and slight distortion even on clean settings, and sometimes it comes back to normal if I turn the amp off and let it cool down for a while. I’ve already tried swapping cables and guitars and checked the speaker, but the problem is still there, so I’m wondering if this could be related to a failing tube, overheating, or a bad solder joint, and I’d really appreciate any advice on what to check first or if anyone has experienced something similar. Thanks in advance for your help.
