What are you talking about? That doesn't make sense.
A JFET is a FET.
Class A amps can be made from tubes, FET's or BJT's.
Many Opamps have JFET's and Class A amplifiers right in side of them...like a TL072 for example.
A TL072 has a JFET input and a dozen other BJT's, diodes, resistors and maybe a Pf value cap.
Operation can be same ....delivery NOT.
If you want to debunk, get your facts right!
