Glad my guess seems to have helped.

Yes, thanks a lot for even just suggesting something I might have done wrong and then even being spot on instead of trying to explain to me that I just don't see the stain.

The quality is not the best, but here is a picture of the negative developed in PMK with amidol (upper) and the negative developed in PMK without amidol (lower):

Pyro developed negatives are supposed to have less visual contrast than printing contrast, especially when used with graded papers. The Pyro stain provides a high contrast to the blue and near UV light to which the paper is most sensitive. The stan can mask the highlight contrast when used with VC papers--maybe an advantage or disadvantage depending upon the particular image.

Since it is well known that PMK alone produces tanning with a relief image, from what you have mentioned in posts 10 and 30, there seems to be a difficulty in seeing tanning when amidol is added which makes the observations rather inconclusive.
