My amps are less than 18 months old purchased new in box. I have also found other minor faults with the power LED's failing and tube sockets needing to be replaced (both Chinese made). In addition, there have also been some wiring faults present.

On a separate note, would you know if its possible to upgrade the AC mains transformers? They look identical to the ones used in the TRK-3488 kit. Any close up photos showing these transformers in further detail would be most helpful. Are they hand wound in China or Japan? Again, I have noticed a wiring fault present between the 2 power amps with a different layout of wiring posts available on the side containing the 4 large holes at the bottom (that is, to the left of the photo I have included).
