Build your own and save!
parts: 1 100 uf 35V electrolytic capacitor, 1- 1 watt 33 to 75 ohm resistor. resistance value will determine dead key.
Install : remove JP 32 replace with cap + side towards back of radio then solder the resistor across the leads on the
underside of the circuit board.
Check the deadkey and swing on a meter with pep scale.if the deadkey is too low replace with a lower value resistor.
Handy mod for running amps with low deadkey requirements
