symbols on electrode packets

so +.- and ~ for polarity are straight forward
but what does = mean?

well the symbol for DC is a solid line above a dotted line (look at any mains to DC adapter) Could be they did not have the correct synbol so used the "=" maybe

IIRC The dotted line/straight line means unregulated DC

mike it looks like you could be right
looks to be seperated from the ac symbol
