I have a 2600A NAD amp here that has purposefully placed solder shorts going from collector to emitter of Q330,332,331,and 329. Is there anyone familiar with these enough to know if this is a factory modification? Amp also has the relays subbed out to ones which are far smaller than the factory originals. Hot glued and hard wired to the metal frame / pc boards. It also has Q318 and 320 dead shorted.
