[Boatanchors] G.R. 1606 A Bridge Question

[Richard Knoppow]

    I don't want to open my bridge to look at it and am not sure 
from the photo in the handbook but by memory this is 
non-inductive resistor wound on a mica card. I have had similar 
GR resistors open up at the terminals. Try resoldering and 
inspect it for a broken wire. I have had to replace GR wire wound 
resistors where they were damaged when the instrument was removed 
from the case. If the resistor is open you will read some 
capacitance. You can try a film resistor in its place to see if 
the bridge works but it may not have the correct residual 
reactances.

> The General Radio RF Bridge manual parts illustration shows a picture of the location of bridge resistor R-3,a 330 ohm wire wound resistor,looking like a piece of plexiglass mounted on an L-Bracket with a solder lug on it. It reads capacitance but is  open in resistance. Is this actually a resistor?  Special made.?  Thanks, Al, W4TUK
