In this blog post a crt TV a part and turn it into a oscilloscope. I am going to try to use a TL082 op amp to buffer and amplify the signal. It uses the deflection yoke to draw the picture on the tube.
224vac on vertical coil and 21 Hz sawtooth on horizontal coil 
Buffer circuit one with ok impedance 
I took the TV adapter for old antennas i used the screws for the signal inputs 
function generator being used 
Circuit with adjustable impedance and ac/dc coupling
More pictures and videos will be posted here when it is finished
