Lear 25 captain reported electrical failure 13;000 ft; including generator failure; bus failure; and...

Narrative:

Leveled at 13;000 MSL. OAT near 0; turned on nacelle heats. When issued new frequency; and checking in; heard the sound of at least two circuit breakers opening; followed immediately by the sight and smell of smoke. ATC did not hear my transmission; and leds on radio soon failed. Pressurization began to fail; right hand generator failed; and got takeoff trim warning (in-flight). Emergency pressurization system soon activated. Began transmitting on other comm; but receiver had failed. Transmitted on guard frequency to announce altitude deviations. Later learned that transponder had also failed. Many engine gauges had also failed. Due to unknown status of squat switches and anti skid system; decided to divert. Announced both on tower frequency and 121.5 of our intentions and position. Landed without further incident. Later learned that right generator control panel had failed; causing over voltages; bus failures; and numerous system failures.
