Tom E,
Yes, I did expose all the original manufacturer's screws to a magnet and was surprised to discover that three-quarters showed an attraction, perhaps a third as strong as had ferrous screws. Since this was a cross-application exercise from UncleStu's speaker tweak, I started off with brass screw substitutes for case machine screws but their presence degraded the sound by changing the tone. So then adopted nylon/ plastic for all machine screws and was apprehensive of their capacity to resist stress. I need not have worried as, despite regular screwing/ unscrewing the plastic/ nylon machine screws of all sizes and holding the unit upside down/ on its side for access, the screws did not sheer with one exception. I was tightening a screw into a screw-hole where, unbeknownst to me, there was a remnant of Teflon tape whose added resistance caused it to snap. Thereafter I took great care to inspect and clean all screw-holes.
It was frequent testing of the warmth of the LFD LE4 heat-sink with my fingers many times daily over many days before I concluded that it was safe to substitute plastic/ nylon for SS machine screws there as well. Since most amplifiers run hotter, that is not a safe application that can be recommended for most users.
Am unclear as to what you want me to do with the electrical testing because that is outside my experience/ have no equipment for solder for bulbs to wires to batteries and must now sleep. With the slightest electrical concern, I simply detach the components concerned from the circuit. Much appreciate your spirit and will do what I can that I do get to understand and does not cost much money. (I find that the AC internal ground is tightened directly against the case by a plastic/ nylon screw with a brass washer in between the ground and the plastic screw-nut.)
Take care,
DG
