Those are your words. Once the patent is over then it is not a "rip off".
There are many examples of circuits being revived. With tube power amplifiers, the Williamson circuit and the Mullard circuit come to mind. Those circuits have been used over and over again, once the patents ran out, by many amplifier manufactures. Once the patent ran out there was nothing wrong with that and no one has ever expressed a concern over it.
So I really don't get what you're saying.
I'm not even sure there is anything patentable about the EAR preamp. To be patentable a circuit has to be something "new", something truly different and never done before.
