Vibrator inverters
Some of my collection. From top to bottom left to right: 2x Ferris 30W, Smoothflo
Top to bottom, left to right: Two lots of Ferris 12-240V 30W, Smoothflo 6-240V 40W, Du Mont 6 or 12V to 115V 60 c/s 175W, Homemade 20W, Bland Radio 15W 240VDC shaver inverter, Glenradio 12-240V 50c/s 100W, Robinson shaver inverter 6-240V 15W, Champion 12-240V 20W, Ferris 12-240V 30W, Homemade 12-240V 60W. Except for the DuMont and Glenradio which use mains frequency inverter vibrators, these all use car radio type vibrators operating at around 115 c/s.
Since this photo, I've collected a number of U.S. made Terado and All State inverters. Why would someone collect 115V inverters in Australia you might ask? Actually, I have a small but growing number of 115V appliances. And, many items sold in Australia in the last few years with switchmode supplies are designed to run from 100-240V.
