Heathkit laboratory CRT Oscilloscope model and 50 similar items

As received, older heathkit scope Looks to be 0-10 model but not sure as little back plate/cover is missing. Selling what is in picture. We powered up(slowly on a variac) Pilot lamp lit, tube filaments glowed including CRT. but main transformer started to get warm (not to hot to touch, but smelled a tad warm too so we did not leave it on more than a few mins) Did not see a visible "trace" on screen. So may have bad transformer, or shorted cap etc? not sure , not going to spend time diagnosing as this is an old model. looks to have 5UP1 CRT has dust and signs of age/use Great steampunk decoration! Put some green or blue LED strips by/behind CRT face for a awesome night light! SELLING AS IS AS YOU SEE IT!
