alright its all still confusing but at least i have some intelligent people to help

. i just finished sanding down the cabinet too, it looks incredible. its going to be a blonde with the original mahogany color on the inside and around the speaker. here is what the underside looks like, some of the caps dont have any writing on them, but im sure between the pictures and you knowledge we can figure it out! also, i took a picture of the volume control, as that will need attention too
