HP 6177A repair (fixed)

 |O I could have made good use of those parts, that case size isn't exactly the most common...

Oh no, I have those and keep those because the frame might crack and its annoying to bond (big reinforcement plate).

I mean the sheet metal stuff was in foul condition. Its plastic coated or something and I believe its a measure of safety (isolation), so if thats damaged I get rid of it. I don't think paint is up to the 'spec' it needs, given how close the conductors are to the chassis.


The cast HP side plates I keep, it only takes 1 drop to fracture that sometimes.


On some unit the side plate is within 1cm of the transformer main wiring. If that cracks off, its easy to get a hot panel. So if the insulation on any of those panels is missing I don't use them. The ground is a bit shady to trust that much.



I polish those panel too, not just the rails, but rails you can sand down, the panel can only take a gentle buffing with car paint polishing compounds

coppercone2:
actually I can't renember if i threw it out, it might be under something, i can't seem to find the casting

i was wondering if the a one is compatible with the c one


the mod4 crimper is a pleasure to use, but it does not have a loader thing, so you need to load it with tweezers first

factory:
It was the side cover panels that I'm missing (exactly what is not in the picture), they usually clean up fine with foam cleaner & some shoe brushes I have. The size is unique to these narrow cases.

The cast alloy frame should be the same on the A & C.

someone should 3d model them so you can just get it cnc machined from aircraft aluminum and forget about it

i know people would pay. i probobly would

when I had to fix the one on my RF amp (or was it function generator?) I thought I would pay like 300$ for that part if someone had it :-DD
But I ended up doing a splint with a piece of mild steel and 5 screws.

getting that part is similar stress relief to going through 20 bottles of alcohol

I did find them but I know i will curse myself in a few years if I do sell it because a good current source... might be forever. And it could get adapted to other frame with some work
