Ameco PCL Preamp
I have one of these that I wish to get working for a 160m receive antenna.
Anyone knowledgeable with the Ameco Preamps.
It has no power supply, only has a two wires with gnd coming out of it.
One of the leads go to the on/off sw for the filaments of the nuvistor and the other appears to be for the plate supply.
I downloaded a schematic/manual from bawa close to what mine is. From what I've gathered it needs 6.3v @ 2a dc/ac for the filaments and 125 @ 50ma dc for the B+.
One thing is, it looks like someone added a 12K 1w resistor in the B+ line for some reason.
I can scan and take pix of what I have if someone could help me out with this to get it going.
thanks ... 73 Dwight NS9I
