Your car has two accessory. First and Second. One is sticking. The Radio and A/C are on seperate circuts that's why your radio doesn't work and your A/C does. Your A/F is also most likely on the same circut as the A/C.

I would disconnect the power source to your Turbo timer since it maybe one of the turbo timers relays that are stuck feeding power to the accessory circut.

If the problem persist with the power to the Turbo timers relays out disconnect the ignition switch. They do go bad. I had my ignition switch go bad and a similar problem happened.
