Crown SA-30
Little is documented about the Crown SA-30. Most of what is known comes from a single new-product note in HiFi/Stereo Review (June 1967, p.22). The note lists it as the Model SA 30-30, a solid-state power amplifier rated at over 20 watts per channel (sine-wave power) into 8-ohm speakers and over 30 watts per channel into 4 ohms. It also claims a damping factor above 200 at all frequencies below 1,000 Hz and frequency response of ±1 dB from 10 Hz upward. The upper frequency limit is cut off in the surviving scan.
Past that announcement, the record goes quiet. No price, no production years, no manual and no further period coverage have surfaced. The SA-30 appears to have been one of Crown's lesser-known solid-state amplifiers of the 1960s.
Known from the period source:
- Solid-state power amplifier
- Rated over 20 W/ch (sine-wave) into 8 ohms
- Rated over 30 W/ch into 4 ohms
- Damping factor over 200 below 1,000 Hz
