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?

Thanks!

Only the original N75 need the mod.  All N75a include the mod.  Serial number numbers 1-100 are N75.  Serial number 101 and above are N75a.  You are good to go.  de wb0yfl

What about removing R47 and the first hundred kits?

Yes, that would make them more like the N75a.
