cant believe that hickock works...awesome the dc offset moves the trace but falls back

I wanted to fix my heathkit scope and i (we) will in time but i ordered another one so i could get on with my journey here which is happening at a snails pace


gonna have to do a lot of reading and watching videos

Just above the probe connector is a switch for AC or DC coupling.  In the pic, you have it set to AC.  That is why it will not hold the DC offset, you need it to be set for DC coupling.
It is not that often that I use DC coupling on my scope, but useful for some things.  Generally I use my meter for DC measurement.
