| Notes: The Resistor T-Pad network section provides 18dB of attenuation. There are two 460 ohm resistors in series and a 150 ohm resistor to ground between them. (Thanks to W5JAY for this info!) Upon request, Jensen will provide the 620pf capacitor with the JT-11P-1 transformer. For TRS 1/4" wiring: Tip is Plus, Ring is Minus and Sleeve is Ground.) A Radio Shack aluminum project box (Cat No 270-235) may be used to house the transformer and pad circuits. |
