Schotz circuitry technology or not?

By JOEL “HORB” HINZE, 1. April 2026, 17:04.

Does this tuner have Schotz technology in it or not? It has been noted that there is another piece of equipment that is a table top that does have Schotz technology. My question is simply does this At-300 Proton tuner have Schotz technology?
