Gibson EH-125 Input & Volume Modification
I recently published a YouTube video featuring a noisy Gibson EH-125 tube guitar amplifier. To resolve the noise issue, I found the best solution was to rewire the input jacks, also reposition the volume control after the 6SJ7, then feed the inverter tube. The result was a quiet and responsive amp! If you decide to perform this modification or want to simply build this cool little amp, just follow the diagrams above.
