rd-75 diaphragm replacement

[poor_lackey]

Hi Guys,

I have been considering a pair of RD -75's.
1 is described as open CCT - with cause is unknown
- so being less than optimistic, I am also unsure about the second unit.

While it's the preferred option
- freight to the factory and back for re-film,
is not economic for 2 units, and marginal for 1.


Does anyone have any thoughts/experience with DIY replacements?

Not sure if it's a project I should consider - or if it's possible?
- and a little difficult to conceal from the boss if I can't deliver ;-)

I have a couple of ideas,
but not sure on the construction of the diaphragm?
or the method used to suspend/tension it,
so my thoughts are a little premature – and groundless (read potentially stupid)

Appreciate any comments/suggestions/insight.


Thanks
Tony
