Zeftronics voltage regulators

[GJ Humphrey]

Does anyone have experience with Zeftronic voltage regulators in C337s generally, or the T337G in particular?

There is no means to adjust the Zeftronics regulators, where the Cessna regulator has an adjustment screw. The mechanic says the Zefronic regulators can adjust themselves autmoatically. Is this so?

Are Zeftronics voltage regulators a good replacement?

We put zeftronics regulators in two of our planes. I don't know the perticulars about them but I will ask our avionics tech about them on monday. They work great in our planes and we have the bigger alternators. I apologize for my ignorance, I am just a lowly sheet metal mech.
