I use LFI, but that has intensity sliders as well, so it should be possible to do some tests with that. However, i'd prefer to have a frame that contains some sort of brightness bars so i can see them all at once - both in the projection and gliding by on a scope and all.

... still no good test frame, but i decided to upgrade the hardware anyway - and it does make a difference on certain frames, probably because they contain mixed colors. My system doesnt have blue though, so its a still a bit finicky to properly test.

One advantage is that i can turn down the green to get a true-yellow rather than lime at max power, sacrificing some brightness obviously.

Yes, the advantages are well seen as soon as you try it out.

I suppose so - i'm fairly new to constructing scanners and such equipment, but it has been a very good exercise in electronics so far. One thing i noticed with the upgrade is that some frames were worthless with ttl blanking, but quire nice with the analog drivers in place.

I have to wrap all of it up as a guide at some point, and i think the analog capability is going to be part of that - it seems well worth the couple of extra components for people to recreate it all. On the other hand, its been quite fiddly finding out whats exactly going on using a scope, but thats reasearch that needed to be done only once i hope
