So, stupidly enough, it looks like there was a totally random grounding tab that was not seated correctly that was shorting some seemingly random point to ground, shimmying it out of the way seemingly restored the scope to its prior functionality. With that out of the way, i'm now back to the position where i was when i first got the scope, being a bit inexperienced with analog scopes and mostly having used digital ones, is it normal for it to be difficult to get a stable waveform at lower frequencies? for instance, probing anything that's about 50Hz, i cannot get the waveform to both a) be steady on the screen, as in not scroll across the screen and b) not blink/flicker, is this a common thing with analog scopes or should i be investigating further repair. Also, when probing the scope's built in calibration generator (1kHz/500mV square), i notice a strange effect, where even though i can get a steady image on a large section of the timebase options, sometimes the intensity of the waveform will change pretty drastically, for instance between 20us and .2ms the waveform is fairly intense and also flickers regardless of how i twiddle the trigger level and holdoff, below 20us it gradually fades in intensity for each step until .05us where it basically fades out of existence, above .2ms it immediately snaps into a lower (seemingly more reasonable) intensity and stays that way on all settings below on the dial, when the intensity drops for instance it becomes impossible to see the rise and fall of the square wave, which is reasonable at a low intensity although unexpected for the intensity to vary that drastically. I don't necessarily expect much handholding but i would like to know if this is normal/tolerable behavior for an analog scope or wether i should look into further repairs. Thanks
