Listened to an October thunderstorm. Yeah...that seems normal.
[edit] which has now turned into a flash flood warning. Could be an interesting night. At least the lightning is impressive.
Nice Marshall. I switch to an electric trimmer after my gasser went tits up after just 4 years. I have a feeling it had similar issues to what you're trying to solve and I didn't have the patience or time to try to disassemble the whole mess.
