I guess I can live with this as long as amplifier 4 doesn't fail ;-) In unscrewing the amplifier modules to pack them up since we're moving soon, I accidentally stripped one of the screws holding in the middle amplifier module of my MPS-2. So, I guess since it's right in the middle at least the weight is balanced, and there is less weight in the box of 5 modules. I suppose that if I knew what I was doing it would be possible to drill out the screw, but I don't, so I'm just going to leave this alone. All this packing of high-end gear, especially all this really large and heavy high-end gear, is a lot of free exercise I guess.

Had a possible inspiration... With the chassis empty around the one card in the center, maybe I could get a small pair of pliers inside and grasp the screw and turn it from its threads on the inside until its out enough that I can grasp it from the outside. This will have to wait until next summer as it's all going into storage for the move and wait on a house build, but maybe I have a plan after all!

If you try using pliers to grasp the threaded portion of the screw to try and turn it out be careful not to damage the threads where they will not go through the threads in the hole that it is screwed into.
You could also try using an impact driver,the manual kind,to get it loose if the head is not 100% shot.These work by hitting them with a hammer which drives the bit down against the screw preventing it from slipping out of the screwdriver slot/opening cut into the screw head and then the internal mechanism applies amplified torque to loosen the screw.Once loosened you can revert to a standard screwdriver for removal.
If the head is so damaged that the above method will not work or if you think the part is too delicate you could try using a Dremel tool with an abrasive disc to cut a new slot across the screw head for a flat blade screwdriver.
Good luck.

Much thanks to LCSeminole et. al. for the suggestions. It would probably be dicey to get a locking pliers in and not harm anything. I've saved a link to the video.

I've used the extractors to remove stripped screws on audio equipment before and they work like a charm. I'm sure you won't have any problem getting that amp module out when you have the time.  |

BE CAREFUL when drilling and tapping. Or using a Dremel. What you Do Not need is metal chips or filings shorting out something VITAL. If you are near an Edge, you might just open up the hole and use a Tinnerman Nut. They come in many varieties but may be what you need. araymondtinnerman.com/industrial/resources/Catalog-Final_10.29-w-Revisions.pdfOther fastener and attachment options exist. If I were doing this, I'd strip out the other modules and have someone with a VACUUM Cleaner stanidng by as I did any mechanical work. |
