G'day Ray.
SWMBO is looking after you well. That looks like an interesting read.
I have noticed lately that so much decent equipment is being scrapped because the basic skills to repair the item are being lost. I just offered a local security firm to rebuild some circuit boards (alarm systems) that had pretty minor faults. Their reply indicated that a replacement (from China) would be much more cost effective as they could charge more. One board had a blown fuse. The 'technician' was only trained to replace the board (at $150 p/h btw). Further investigation revealed that he was only paid $30 p/h btw.
We live in a "throw away society", it's sad!
