More than a few to name, but the one that really sticks is when I burned up a set of drivers that cost $600 ea. They were new for um, maybe a couple days before I got the idea to add a tube buffer that I had worked on, but did NOT test! You can't make it from the listening chair to the power switch in time, no matter what.
What has been your costliest mistake in this hobby?
For example :I recently learned a hard lesson- I accidentally ran voltage thru my $3000 MC cartridge (kiseki purple heart). I have a TT with 5 prong connector and a phono cable with a 5 prong connector. I accidentally swapped where they plugged into and ran electric thru the tonearm into the cartridge. It was a stupid - not thinking- hasty mistake. When I corrected the problem the cartridge was fried. An avalanche of four letter words followed!
So what has been your biggest and/or costliest mistake?
