You ain't shitting. What I don't see is how they can go to all the trouble making counterfeits that actually work but are like underrated for the job. If you are going to make ICs why not just make them right ?
So now I got this Pioneer QX-747. It had so many bad transistors it ain't funny. Three channels of the power amp and then one other board they call "equalizer" and now the SQ decoder. Not one power transistor or capacitor bad. It ran me out of elcheapo small signal NPNs ? I don't even remember how many I had, but I just ordered 25 more. (hope that does it lo, naw it will) I guess it is my fault, the guy said quad is not that important but I told him you want that RM function at least, sometimes it sounds good, and sometimes playing movies through it is really nice.
The manufacturers want us dead. They know how warm a vertical IC will get and the put the boost cap right near the heat sink. So this is not that conclusive but on the other POC somewhere I got part of a schematic of a Mitsubishi power supply that is. It has a connection in the feedback loop of a 5 volt or whatever that is made specifically to make the Vcc(ee, whatever) fluctuate to corrupt the data in the IC. Another nail in the coffin ? They sent out a bulletin that the customers were to be told where to download a file to a USB drive and boot the TV with it is themselves, cutting us completely out of the procedure.
The manufacturers waged war on us, I took it that way. I figured I was a general.
