Yet another purchase off Ebay, with a noisy volume, not just noisy when the volume was touched, but extremely LOUD cracks through the speakers. Spoke with John about a repair initially and dropped the amp into his workshop, socially distanced and masked of course.
Spoke again with John as to the problem and was given a cost to repair, but decided to have the A3cr upgraded and I am so glad that I made that decision.
The amp sounds superb even during its running in period.

Great service from John, many thanks
