Well i received my parts back today from lary n7dd I opened the box and noticed the poor packaging. So i checked out the parts and my new microy piece i had made a month earlier was broken in the middle. The kit contained a new plate choke new flappers and adjusment of the cap values on the plate side by changing capacitors with different value caps. I checked out the plate choke with my uh meter and read 90 uh almost the same of what i have now with the same size wire. A few windings had areas where the enamel had come off from being hit.So i decided this choke is not needed. I looked at the flappers and noticed the contact area is wider from side to side but the area front to back isnt.So basicly they do not cover the entire surface of the oposite contact in which they mate with. The flappers are not as long.To compensate i would have to move the 2 rows of capacitors closer to each other. I wont be using the flappers. I cannot recomend this mod to anyone. This mod cost me 775.00.Im out 210 plus my time for a new insulator and machine work. I got no refund for my damaged parts only an offer for another insulator from an older henry 8k.And false promises of insurance from usps.Even though the box has not a single blemish.
