I am looking for the perforated (square holes) top cover for the RF deck of a Henry 2K-2 amplifier. I think this cover is the same in all models of the Henry 2K and perhaps in other Henry amplifiers. I am also looking for the perforated top cover for the amplifier. I am also looking for a good pair of 3-400Zs. Thanks and best wishes, Jim Jorgensen, K9RJ
