I rewired the ribbon cable because it looked like it was about to break. The vacuum tubes were replaced with new electro-harmonix ones in December. I replaced two op-amps with MUSE8820D. Please refer to the images. In my subjective opinion, the noise has been reduced compared to before the modification. I haven't replaced any capacitors. The meter is moving, but it's unclear if the readings are accurate. Included accessories are the original AC adapter and the original vacuum tubes. There is no box, so I will wrap it in bubble wrap for shipping. Please consider this item if you understand that it is a used product.
