Hi All;
I have two questions, one pretty basic, but I need to confirm my thinking..
First, I have the Old style of Tubes, 4 and 6 pin, so when consulting a tube manual and it show the pin placement.. Is That looking down from the top, going Clockwise from pin 1 (usually Filament) arround till it gets to the other usually filament pin.. And When looking from the bottom is the Counting Counter-Clockwise starting from pin 1 ??
Secondly, I have the Old style Philco IF Cans which have a single hole for both primary and secondary adjustment of the Mica Trimmer Caps.. A screw and a nut adjustment.. Does the Trimmer Cap Go Bad and How can I tell If it has gone Bad ?? And what size is the Trimmer Cap ??
THANK YOU Marty
