ClownBurner,

You can get the Becker keys by calling Becker at (888) 423-3537. The part number is BNA-1184.989. They cost less than $2 when I bought mine, about 18 months ago.

I am about to go back to the DC-DC inverter if I can find a place to put it. This really does solve the problem but I do not want to run it all the time and I don't like to pull the power on the Empeg so abruptly. Perhaps Hugo can comment on the downside of doing that in the car environment.

I have also considered using a diode gate to provide power when the car is off but this would require setting the inverter to an output voltage that is higher than the highest voltage ever seen from the alternator and counting on the audio cables for a ground return. Again, perhaps Hugo can comment on what circuitry is between the digital ground and the analog ground inside the Empeg.
