Hi everybody, I've just put my hands on this "great condition" scope
except it doesn't sweep. I am used to work on audio equipment like
amps, tuners, etc but this is my first scope and I don't know where to
start. I guess it is where some DC level goes up and down like stairs
( ther is a name I don't remember. the ramp ? )... Anyhow, would
anyone have the schematics or the service manual of this unit ? It
would be really appreciated !!!
