Perhaps every roadie should be put in a flight case and dropped down

Anyway both heatsinks must have bent relative to the pa pcb, bending
the
leads.
How to anchor back more firmly than just white paste? The main TOP66
power
devices etc have those slide on spring steel clips but the loosened
TO92
tranny and fan thermistor are a long way down from the mounting slots,
for
anything like that. Any ideas ? - live heatsink btw, hence not rigidly
held
to body.

Could you drill into the heatsink and make some sort of spring clip
mount?
How about some duct tape Those sensors don't have to be driven into
the heatsink, just held against along with a little compound.


The band is off touring abroad from the end of the week. All I can think
is
to secure bits of nylon cable tie to the pa pcb and bend up against the 2
errant items. Too crowded to drill/tap the heatsinks and the assembly of
these sort of hook-clip arrangements is realy make once,
dissamble/reassemble at your peril.



How about sticking them to the heatsink, with thermal glue such as is used
to stick heatsinks to chips ?
