75A - Kits in the 190 Serial Number Range - Do They Need The Modification?

Bruce W1UJR <w1ujr@...>

I read that the early 75A kits needed a separate circuit board due to receiver performance, with inadequate AGC range and objectionable distortion. 

I bought 5 of these kits to build and also to give away to younger hams. 

When do these mods apply to the kits, is it in my serial range?
