Re: [APML]: Tech Pan Problem

re: piholes in Tech Pan ....

Is this older, stored Tech Pan  ?  I've seen this when older frozen
emulsions have been used ... 

Are these frequent ? or just once in awhile ?

I use very dilute stop bath ...  about a 1% solution ....  I see a small
pinhole like flaw every now and then, but nothing to get me too upset ...
strong stop bath is usually the culprit for emulsion pinholes or the
use of old emulsions ....

more details may help ...
