My notes and memory don't have the answer to your very sensible question - but this was in the lull between Christmas and New Year so I suspect I wasn't on site when the replacement was fitted and the original problem finally solved.  To be fair, in those days the paramps were part high tech and part magic and odd things did happen.  Temperamental was the best word to describe them.

In any case I soon had other things on my mind - the next afternoon after the incident I went for an aerobatic session with a friend at the local aero club and afterwards was introduced to the girl I later married!

I agree William - and a picture is worth 1000 words when dealing with folks who speak different languages. I was investigating an RMA and could not understand why some Asian engineers were continually blowing up our NV Rams - so I asked for a schematic of their test board which they faxed over and it turned out they had power and ground reversed!

Nancy, you are certainly correct about that. But in my case the person was a native of the USA and claimed to have done technical writing for a number of larger companies. Actually, the really poor translations do provide clues that they are not to be trusted by virtue of their poor translations being so obvious. And sometimes they are good for a few laughs.

William, I think the problem you mentioned about poorly written manuals has grown steadily worse - due to off shore manufacturing that is also assigning the technical writing to the engineers at the manufacturing plant. Often the manuals contain an English translation that is poorly written and difficult to follow.

@William: Im not sure how well it will work if its not been properly fixed. It might even damage the amp.

@CTHP: Yes trusting would be needed but up to which extent is the key here. Many would not want to trust the co-workers below them to a great extent

Nancy, some nanuals are very good, but at one plac we had a tech writer who believed that he knew a lot more than he did know. He wrote a set of calibration instructions for a system that I designed and calibrated initially, and his instructions were so bad that they got me confused. I had to pull out the drawings and write a new procedure for our field service guy who was at our customers site. I faxed him the new instructions and requested that he collect all copies of the others to be returned to us for a shred and burn process. Then we sent our customers a set of calibration instructions that were simple to follow and worked correctly.

And just this evening I fought with a set of instructions for a mass mailing that did not match the reality of that mailing utility. MAJOR FRUSTRATION.

That is what I was wondering as well, William K...

And to argue the other side - sometimes a manual is not available or in the case of a high current supply I was working on - it has an error: one (and only one) of the dip switch settings were reversed - talk about hard to figure out! I think it is just a part of the engineering psyche to jump right in and try to figure something out, but obviously if a manual is available, a lot of time and potential heart ache can be avoided.

Manual?

What is this thing called "Manual"?

Is that a short book about a Spanish guy?

But did the amplifier meet specifications after all of the pieces were put back in place? Did something fix it or was there still a problem?
