My first decent scope was a Solartron 711S. It had a 5" flat face tube with a fast blue phosphor and a long persistence yellow one.
I do recall it's MTBF as almost too short to measure, well maybe I exaggerate just a bit. It was an ex military job and it spent the first part of it's life in a air defense missile control cabin, another story.
However all the high stab black resistors were fitted with a Hellerman rubber sleeve with the component number nicely written on it. There must have been some reaction between the rubber, or more likely the lubricant the wireman used and the resistors would go high or open circuit almost as fast as I could replace them!
It was a two man lift!
Ho-Hum
