This is an interesting issue. The reason I had empathy for the OP was because I had three pieces of audio equipment from a popular brand which were all defective with cheap transformers many years ago. The manufacturer would not believe the products were bad, even though he fixed them???The fan base did not believe it either, and they had not seen or touched the equipment! Were they indeed bad, or did aliens make the intermittent spurious noise, hum and sounds coming from the transformers?
Yes they were bad and yes the manufacturer had not found or fixed the problem correctly.
Are these kind of problems coming from a product made in China impossible to happen? I think there are some companies who make shortcuts by getting cheap stockpiles of parts, or even more likely, parts are switched at factories without proper QC. I hope, unlike many here who have outright called the OP a liar????, he gets the situation resolved. In my case, I did not, and lost a great deal of money. Don’t always believe the hype from any brand. I hope some audiophiles out there don’t buy from the company I bought from, (they are made in the USA from parts of unknown origin). Perhaps we all are too smart to make that mistake???
