Parts to repair an HP 6434B 40V 25A power supply

James Newton
 

Just purchased this thing from eBay and the seller shipped it without ANY padding on the bottom of the box. I know they are pretty well built, but that's just crazy... He refunded the purchase price, so I got what's left for the shipping.

Right handle sheared off the case, the ends are bent so I doubt I can drill out the bolts and re-mount it. HP Part # 5020-5512

And the left (voltage) meter was pushed back into the case after the handle wiggled over to that side and got pushed up against the box. The meter /may/ be ok, but the little black plastic bezel that holds the meter in is cracked. HP part # 4040-0296.

And the (-) binder clip is sheared off. No problem repairing that.

I can probably live without the handle. Any ideas where I can get a new bezel or mount that meter? Very strange mounting system. Hope someone here has seen it and knows what I'm talking about.

By way of introduction: I've been in firmware most of my life, I ran the MIT PIClist mailing list for years and still archive it at PICList.com. I make and sell some open source stepper drivers now and so I'm getting more into electronics. I have a 1662C 'scope and a 1653B analyzer that I love. Can't beat the old stuff.
 

Take the bezel apart, and glue it back together. If you
are careful, it should even look ok. Bakelite glues ok
with cyanoacrylates, and most every other plastic does
ok with a thin solvent glue, like testors.

As to the handle, You can sometimes bend them back if you
go in small steps, and let the aluminum relax before the
next bend. The bolts that remain won't need drilling, as
once the tension is off, they should turn easily.

Thanks for the advice Chuck,

I'm trying some epoxy on the bezel as we speak.

Not sure what I have that would bend that handle... it's a monster. How do you think beating it a bit with a hammer would work? It isn't bent much... just enough to jam the bolt in it and cause it to be misaligned with the case.

Picked up the banana post today, I'll try soldering that on once I have the meter back in and then fire it up and hope it doesn't smoke.

If the handle is what I think it is, it is malleable steel.
A hammer would be fine, but use some wood between the hammer
and the handle to avoid scarring it. Or, depending on how
it is bent, a vise and a pipe.

Life would be simpler if folks would learn how to pack.
