Activity P41: Waves on a String (Power Amplifier)
www.kbcc.cuny.edu1. Turn on the power switch on the back panel of the Power Amplifier. 2. Put enough mass on the mass hanger to make the string vibrate in its fundamental mode (one antinode in the center) at a frequency of 60 Hz. Adjust the amount of mass until the nodes at each end are “clean” (not vibrating). Record the initial mass in the Lab Report

Variable Frequency Oscillators (VFOs)
www.qrparci.orgVFO could be a string of class C amplifiers to increase the output power to the final level, say 5 or 50 watts. The VFO final stage will need to deliver at least two volts peak sine wave. Since we have deliberately kept the oscillator and buffer signals tiny, the final amplifier must be a
