Isn't the load on the NT 470K just like the 18W? the 200K is the MV pot. When I changed the gridstoppers on the NT they didn't changed the tone in any noticeable way, in fact I didn't noted any change at all.
Yes, the NT has the .1 caps and the 18W the .01, just like the schems.
I have the feeling that the problem is still the crossover distortion, but I donīt have acces to a scope, so I can't be for sure, but it sounds exactly like the COD buzz, I just donīt know why the PR mod donīt solve it, even with 11V zeners. When I put the 150R bias resistor it made the buzz worse, even with the PR mod.
