[R-390] R390A line filter trial

[Glenn Scott via R-390]

Hi Group,


I made up 45 line filter kits in late 2011 and sold them all within a few months.. I have planed to make up another set or two but been busy working through my backlog of 390 and 390A's   I had metal plates CNC-ed and with the right combination of hardware, this was a 100% reversible mod, NO NEW HOLES, but I can't imagine why anyone would go back to the old leaky and open Corcom filters..If there is enough interest, I will look into assembling another batch.
Installation was very tight but easily doable; looked great to boot. I know these went into Collins, Motorola, Amelco, Steward-Warner, EAC, Teledyne, Capeheart, and Imperial receivers with no clearance issues...The Amelco's were slightly tighter than the rest due to some machining variations..Never did a Fowler...Hi Hi..
