ADS 710-II dustcaps. Repair or replace. Ideas?

Archived from groups: rec.audio.tech (More info?)

I'm trying to refurb a pair of A/D/S/ 710-II's and the woofers on one
speaker have dustcaps that are "pushed in" rather severely. (See
http://stresstherapyclinic.com/ima [...] stcaps.png for a low res pic
to get an idea.)

In days gone by I have been able to rescue dustcaps that have been slightly
dented using careful manual manipulation, vacuum, the "pin trick" or some
combination of all three. These caps are too far gone for manual
manipulation and I doubt the pin trick is going to be much help here either.
I'm considering using some sort of "dry" wetting agent like ethanol on the
caps only and applying vacuum to them to try and pull them out but I'm
wondering if I wouldn't be better off simply replacing them. Anyone know of
a current source for these dustcaps? I want to stay as original as possible.

I'll vote with Arny. The dust caps on the 710's are very robust and if
they've taken an odd set, you have to get them very wet before you'll
be able to pop them out.

If you had the equipment, lots of time, skill, and luck, you may be
able to prove some sort of polar pattern change due to the dust caps,
but it will be very subtile if it exists.

If they are so bad they can't be popped out with any of the methods you
mention, just leave them alone. Sound wise, it makes no difference.
