Old Tek 555
This is an old Tektronics oscilloscope that Erotus gave me.
Thanks Erotus!!
It was last calibrated in 1984. I'm guessing that it was made in the early 60's. As you can see in the photos, it has plenty of tubes, no PCBs, huge caps and resisters. Open leads flying all over the place! I would hate to be the moth that flies into this thing! Got to love those pre-PCB component brackets that make part replacement easy... Just as long as you unplug first... Zap!! Hehe....
