To the other points:
The simple way of seeing that water freezes at 0c and boils at 100c is easier to remember 32f and 212f.
It's easy to see how many meters are in a kilometer....quickly / without math, how many yards in a mile?
Although bars play nicely with the other SI units, it's not equal to an ATM, but better than 14.6959.
The problem is trying to convert. When dealing with temperatures, do I multiply / divide by 9/5 or 1.8 (they are =) and the 32 before / after, add / subtract...
When done on a regular basis, it easy enough to go from one to the other, but if we were never subjected to the system that doesn't play nice it would be easy to cut down on the clutter.
After WWII, the rest of the industrialized world was blown to shat. It was an opportune moment to modernize their measuring system on their machines. We mercans carried the burden of the nonstandard ways of measuring.
Although I have made a few chips hit the pan, I don't claim to be a Machinist. I have a side business and a part of that is a machine shop. This evening i was finishing a repair on a bell housing that's off of an industrial machine. Its major diameter is 28" and I only have a couple of machines that I can machine something that large. Here is a picture of it in a lathe that can swing 32" x 120+" I had just finished the face and the bore was next. From there, a new array of threaded holes to get the stresses away from the repairs.
Any machinist here?
Thanks Justus for the link. I found that earlier but I was wondering if there were any service manuals that gave a little more information on values, test points and voltages.
I did some more troubleshooting and here is what I found. I wondered if the supply was good. Measured voltages on the transformer and they check out. I checked the bridge rectifier and it seems good. The input voltage to the rectifier is 78VAC and output is 103VDC. I expected to see 78VDC but I assume the filter caps might be adding a little. The voltage going into the LF amp is the same 103VDC.
I inspected the LF amp a little closer and I think I may have found the colpret. Looking at the burn pattern, it seems that D03 and D04 might be bad. Those are 15V zener diodes. I will grab a couple of those as well as a couple TL074's in case the opamp is out.
I'll update this post if I find anything out.

What's the deal? One can not come in to a thread you have commented on and offer personal experience with a particular product?
