There are other things which can wipe out humanity from the planet but their probability of hitting us is extremely small. For instance, a gamma burst can easily damage the biosphere by wiping off the ozone layer. There is also the 'spectre' of rogue massive stellar objects which roam unattached to a galaxy. These can be black holes or neutron stars or anything in between these two extremes. A stellar object like these, will disrupt the solar system's equilibrium with yet a more horrid spectre of planetary collisions, planets being ejected out of their orbit into outer space and collisions with the stellar object causing this disruption.
The above is what can happen from beyond the solar system, but this is not enough. The Sun itself can do huge damage to the earth and its people, by emitting strong stray magnetic fields which induce huge voltages in long cables destroying electricity distribution systems and communication systems.

The only problem I had was drilling the holes into the flange. The drill press chuck is too large to get close to the sink, so the TO-3s were laid out length wise. The new sink is ~ 80% larger than original. Have a new 400 VA trafo & new PSU boards with 40 000 uF for each channel. The problem is getting the case finished off, but can & will be done later. Time to get these boards working. The lock down is helping. PCBs will be below flange with TO-3s top side.

I love that build, it has a look to it that is missing from my high density SMD designs that relaxes me just looking at it.

edbarx,

Our demise will be self inflicted I suspect. It could be as simple as redesigning our DNA just because we can, whether for increased life expectancy, greater performance, to make better soldiers or to support space travel. And in time we’ll become a different species and we, the ‘old species’ will be gone.

Yes Gareth, with Crispin we can either produce a super-race, which will quickly cause war, or swap our meagre lifespan for additional decades of immobility or dementia!

Ah, we live in interesting times..... I think we are due for a best seller about genetic dystopia, shame Robin Cook is not alive.

Our restrictions are easing off in Oz. We can visit friends with up to five guests now, but cafes are still restricted to takeaways. In some states cafes are open. Australia stands at 7019 cases, 98 deaths, and 6337 recovered. This in a population of 26.2M. The latest clusters are meat processing plants and McDonalds takeaways.

Hugh
