That's great. Its always satisfying to work on a well engineered and made piece of equipment that's still working with all its original parts more than a half century later.

Its also interesting to note that while Chinese electrolytics are failing in modern equipment after only a few years, good US made caps can still test and operate as new 65 years later.

And it does illustrate than many of these old electrolytics can be returned to service without replacement by proper reforming. I would expect that the electrolytics in your HP 200CD can similarly be saved. You may even be able to reform them in place without desoldering them.
