I use them in my Phono II and wouldn't go back.....so I can well believe they work well in the III.
The drop in gain has never worried me, in fact I saw it as a benefit as the noise floor(hiss) dropped.
I didn't make any adjustments to the circuit or components, but it looks as if the III is somewhat different with a trim pot for 3.18uS RIAA equalization?

Anyway interesting reading...many thanks.
