Hi Josh, all,

I find it rather strange that your "sonotube" secondary held up for
a whole year and then decided to shrink or shift and let all of the
turns slip down and overlap like a slinky. I wonder if you may have
drastically altered the environmental conditions that you were stor-
ing it in or something. Even at that, my 12" sonotube secondary
has held up beautifully for nearly 4 years in an unclimate controlled
garage (where temps ranged from as low as 10* F in winter to as
high as 120* F in summer) and survived a move to another home
to boot. Has anyone else experienced this misfortune w/ a sonotube
secondary, assuming that they properly poly coated it inside and out?
