I picked up an early president grant U858 - three button front. Seems to be in good working condition, and has at least two mods that have been applied in the past, maybe three. One i have found to be the rf gain control mod. The other i am pretty sure is a channel mod, but i cant seem to match it up to any of the existing instructions floating around. Also wondering if anyone has any documentation on this earlier model grant? All of the specs, or tune ups, or manuals seem to be for the later gen grants.
