Hi, I've got one of my Trinity 18Watt sIII making a electric trickling sound when I unplug the guitar.
This is especially noticeable with the TMB channel.
The amp sounds great when the guitar is plugged in and all controls work great when the guitar is plugged in.
This crazy noise only happens when I'm unplugging the guitar from the amp while the amp is still on.
Can anyone give me some troubleshooting suggestions?
Thanks very much.

I think this may be fixed. I double check my ground solders going to V1
Wish me luck.

It is much more likely to be a poor connection than anything else. Heat makes the connection move, which can cause strange noises and other issues. One way to troubleshoot this issue is to start visually examining and tracing the build against your schematic and layout and mark them up as you go.

Use a magnifier to look for “whiskers” at joints that could be shorting.
Check component values while there as it might save time later.
Then move to chopsticking components and joints looking for noises with the amp running.

If you still have an issue after that, take some pictures and post them along with the schematic and layout for others to provide more detailed help.

I believe the issue may have been resolved. I've gone through the process of reevaluating the ground solders connecting to V1, and now I'm crossing my fingers for a successful outcome. Visit https://srdstatuscheck.org.za/
