1. The preamplifier's normal volume control is of course used for all routine listening-level adjustments.
2. TR1, a preamplifier centred on transistor TR2 and a high-gain power amplifier IC1.
3. Use of the INA103: this is a microphone preamplifier with the microphone phantom powered and a DC-restoration circuit at the output.
4. The tests were done using the ProSciCard Program (Pro Science GmbH, Linde, FRG) whereby a standard electrocardiograph (ECG) recording was amplified by an ECG preamplifier and fed to a Pro Science laboratory computer.
5. Low-noise (formula provided), low-distortion microphone preamplifier enables phantom powering of the microphone and allows the use of a 20dB pad at the input.
6. With an all-tube preamplifier and a transistorised power stage, the chunky-looking new "Bassic Black" combo from SWR kicks out 140 watts into 8 ohms through a 15-inch speaker and a piezo tweeter (there's an extension cabinet available containing another fifteen-incher and another tweeter).
7. The unit can only be used successfully with low level inputs, such as microphones and low output guitar pick-ups if it is preceded by a suitable preamplifier.
