The Eico Model 232 Peak to Peak VTVM (Vacuum Tube Volt Meter) was first introduced in 1954 both as a kit and a complete unit. This meter was revolutionary at the time because it could measure Peak to Peak instead of RMS AC voltage and it's high input impedance, 11 meg DC and 10 meg AC did not load down the circuit you were measuring. The assembled Eico Model 232 VTVM was used in many vocational electronic programs during it production years. In fact the Model 232 was still being used in my high school T and I (Trade and Industry) Vocational Electronic program in 1986! I found this fine specimen at a rummage sale and look forward to cleaning it up and bringing it back to original specifications.
