@yyzsantabarbara “When you get a computer laptop, server, etc from DELL for example. It comes from the assembly line in Mexico or maybe China. They do only rudimentary QA on that line (likely after final assembly.” That is not so. After completing machine and hand placement of components on the circuit boards, they undergo extensive in-circuit testing using HP or Genrad test equipment. Once final assembly is finished, the boxes are functionally tested and many go through operational cycling or even thermal cycling and are run through functional test a second time.
New pre-amplifier?
I ordered a new new pre-amplifier from a dealer and they’re going to send it to me directly from the manufacturer which is fine.
However, how do I know this isn’t a used component that was sent back to the factory for recertification and a technical review or even a repair on a defective return by a previous customer and then sent out as a new product. The dealer has title to the product I believe so the manufacturer is just accommodating and working very closely with the dealer. I know that used products are often sold with a full warranty if done through a dealer and represented as such, which is fine. I assume these types of things are not like a car that has a master repair history connected to it? If I buy a new product how am I assured it's a new product?
Dealers tend to use manufacturing sites to warehouse products waiting for shipment to a customer at times. It can be mysterious. one manufacturer was willing to send me new equipment without involvement of a dealer, which is fine with me but certainly the dealers would have a problem with this.
