I had to report one here who was advertising a cart as being new when in a thread, he let it slip he had put a few dozens of hours on it. Today, I reported a guy selling Elrog 300B tubes he blatantly stated are from the 2nd production run after all the defective/dead tubes most people were encountering were a thing of the past. The owner of the company confirmed to me via the serial numbers that these are in fact very early production tubes and should be avoided. Also, he mentioned the newer ones without these major QC issues can also be identified with a yellow box, when the ad showed an entirely different box. This is a seller who does nothing but sell tubes and already has one negative feedback to his account. I don't doubt he knew what he was doing when he wrote "This is from the improved second production where those issues were resolved." These used tubes are being sold for 1K CDN, too! An uninformed buyer might get these and have issues in a few weeks, making them as useful as a paperweight. How often do you report a fraudulent ad or seller?
