Very "sound" advice. Often manufacturers change the chipset on a card without changing the model number. While I can't pinpoint specific sound cards like that, I do have several with the same "chip"

Obviously , you have never had to buy replacement MOSFETs for a 10 year old amplifier. Tubes seem to hang on forever, MOSFETs get replaced with newer and better models, which are not always useable i

I don't quite understand this, what is being switched? When VoIP became popular, around 1998, the demand for full duplex sound cards caused half duplex (ones that needed to be switched) to disapear.

Yes, I looked it up and that was it. They felt that the radio was too expensive, but did not say it that way. What they said was (and I'm paraphrasing) was that for $1700 (in 1991 when they did the r
