I like the way you think! I have a pile of older equipment, most of it works, the rest is still "in progress".
This brought to mind a Sony amplifier I bought surplus 30 years ago. Until this year, I never had the thing work! Before I bought it, many others had tried and failed to get the felt channel to work. I know this because an aquantance of mine had tried repairing it when he was a tech at the university where I purchased it from.
Over the years, I would pull this out and see if I could get any life from it. The problem ended up being the bias diode that was secured to the heatsink. Although it tested fine with an ohm meter, everything pointed to this component. I ended up replacing this diode with a red led and a 1N4148, connected in series as I needed this potential drop to match the original diode, which has long since been discontinued. I am sure that the thermal characteristics of this arrangement do not match the original, but the amp sounds great, and matches the right channel when bench tested.
Some times ingenuity goes a long way, especially with vintage equipment!
Steve, I can see why you did not pursue the discussion with your manager. If you had fixed a design flaw in the scope it would have called into question all their other purchases. This might have been a problem when using the equipment to verify designs.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
