So far so good....
Yesterday I installed an anti-static mat on the desk, and one on the floor near scope, and bonded a cable to a pier thread (soldered an inline 1M resistor in this cable). Installed a little busbar in a wall cavity for the cables from these items to terminate on as the common-point ground, and tied in the safety earth.
As an interim measure while I wait for some ESD shoes to arrive from ebay, I wore an antistatic wrist band too.
No problems..... I tried to recreate the problems of past, couldn't..... fingers crossed it will stay this way!
