This is strange to me.  Maybe in over 50 years of working around swinging, analog meters I just never saw this, I have missed other things also along the way.
  This morning I unboxed a V7 Heathkit and began investing it's innards.  Looks clean has a dead carbon zink battery, not leaking yet? pulled it quickly.  Noticed the 3 capacitors are original, so I plan to replace them check tubes and replaced the half weak 12au7.
Noticing the meter not setting on Zero, I decided to set it on zero.  When I place my hand on the case to support it while I twist the adjustment screw the needle moves.  I set the needle to zero but when I move my hand away the needle moves away from zero.  Tricky little guy!  So I don't put my hands close to the meter, instead l use a long screwdriver and zero the meter.  With the meter set at zero I place my hand next to the meter and it jumps up swinging rather high stays up until I bring my hand back.  It doesn't return to zero when it comes to rest.  This is with no power on.[attachment=32248]
