- When using rf negative feedback resistors, is there any difference between using 2 ten ohm resistors in series on one side of the fil. as opposed to using 2 resistors, one one each side, fed by two s

- Carl was asking about feedback resistors in cathode/filament circuits. The answer it that it seems to vary. The Mullard data sheet for the QY3-125 (which is basically a 6151/ 4-125, as opposed to 4D2

- I get the feeling that some may have misunderstood my question about the resistors. I was referring specifically to the RF negative feedback resistors as used in the ckts. per Mr. measures's pages. I

- Carl, Mtybe I didn't say it well enough. Which side of the filament the RF return (which is the input in g-g) goes to seems sometimes to be specified, and sometimes not. In the case of the 572B's, if

- Since both sides of the filament are at (or should be) the same RF potential, I don't see where it would make any difference. Usually there is a capacitor connected acoss the filament to ensure both
