hey rf where did you go with this project, looks good i thought there would be more people having a go at building their own, i think i will bias the am400 using the motorolla circuit next, i hope your health is ok so you can get this finnished 
come on people theres plenty of folk on here willing to help if ya get stuck, even boo offered to help, if you buy a parts pack all you need is to be able to solder good enough for it to stay together, if i can turn a useless 2290 2pill into a perfectly sweet sounding class AB 2879 amp whats stopping you doing this? :?: just think of the satisfaction you will get from telling your buddies you built it yourself when they are complementing youre audio

OK guy's,,,I am currently finishing it up...and getting the pics of each of the stages....again,sorry for the delay....I hope to have it done and up for you by the first or middle of next week...
As for the bias,,,,i will be showing it as class C first,,,for the guy's who just wanna "Hammer",,,then we will go through the steps to add a regulated bias circ. and no body mentioned filtered,"FL Native",,but we can add that as well if wanted...let me know!
I have been trying to rebuild my website and building some back orders since i got out of hospital...This project is a priority and it will be completed,hopefully by time stated..
Thanks for your patients,,

dont have all my parts yet but yes step by step. stage 2 being the bias and stage 3 the filtering would be cool. i know bob would be in on that. as im sure the rest would be aswell or atleast most. 8)
the filtering will help reduce greatly unwated out of band/off freq spurios emissions. in other words the "fake watts". the ones that show up on ch2 of your tv and such LOL.
hopefully you would end up with around -40db attenuation above 30 mhz.
some people think or get confused when discusing biasing and think that by an amp being AB biased that the "clean" sound means "clean" output aswell. but that is not the case.

i have read that before about a properlly tuned input and output tuning on transitor amps and even tube amps. but most tube amps still include aditional output filtering.
of course we can allways add external filters but thats kinda combersome. unless you have a large desk. haveing a big external filter out the back of your radio or amp. so i guess haveing the internal filtering is just more convienent.
sounds good to me, filtering on inside. I dont have a driver radio that puts out enough watts to drive this thing but I will build it anyway.
but I will build it anyway.
