[HAM] Recapping

[Kon Zissis]

Hi David.
 
Thank you for explaining that the main area of moisture absorption  in
the wax caps was from the middle section where the leads are connected.
I had assumed that the whole case of the wax caps absorbed moisture thus
causing and that consequently the mfd value to drift up and that  the
wax caps with the stiff cardboard outer  cover  would have had some
extra protection against  moisture absorption.
 
Your explanation  that the middle part of the wax caps where the lead
goes through the wax  is the weakest spot    seems to throw out my
theory about wax caps with the stiff card board outer covers  being
better preserved  because the stiff outer card board tube does not
extend and cover the section  where the two leads are connected to the
wax caps.

to rust than blue Mustangs?

No not at all.
 
All the best.

The real weak spot of the wax-dipped capacitors, however, was the  
unavoidable point where the lead goes through the wax. When wax gets  
warm, it gets soft enough for any movement to open a route for air to  
enter, and it can crack when it gets too cold. I would imagine  
something like a cross-country trip in a truck during the summer  
would not be good for these.
