I was once tuning a Racal tube receiver IF strip ( as
I recall they were something like 115Mhz. You were
suppose to use an orange stick but they were stiff and
needed more effort. I would use a metal screw driver
and remove it each time to check the meter to see if
I was getting better or worse.
I'd forgotten that the last one to tune was connected
to the plate of the mixer. It was 275V as I recall.
I threw the screw drive across the room behind me
and it stuck into the wall up to the handle.
I had to lay down for a rest after that and think about
how to comple the tuning.
