Yeah, that's what I was thinking. The 8F150 and such have large voice coils and huge magnets that are going to give some serious low end rumble. The vintage designs that this amp is based on were designed around the Jensens they had access to in the day, and it all worked out fairly well. I think when you get too far from the vintage "recipe" you risk upsetting the balance.
Now with mine, after doing the mods, I went to that Kendrick 8", which is similar to the CV8 and Sig series. Like you, after I added the 47k NFB resistor (which I can't live without, and love the way it tames the rawness) my amp had strong bass (though that speaker has a relatively small ceramic magnet) and lost a good bit of brightness when turned down low. This is a common problem, and is why I installed the 22pF as a treble bypass on the volume control, which evened everything out very nicely.
I have since moved to a 47pF silver mica on the volume pot, and the amp sounds beautiful. Nice glassy, chimie cleans with good clear low end, wicked when cranked, and with a touch of attitude in between.
I found the rawness with no NFB to be intriguing, but not terribly useful, and kind of fatiguing on the ears.
But that's the cool thing, we all have different playing styles, ears, guitars etc. and almost everyone can tweak this amp to their liking, one way or another.
