Re: Mullard 5-10 amplifier
80mV of hiss is too much. The figure I gave earlier - 75dB below 10W - was for hum and noise (noise includes hiss). It works out to 1.6mV RMS.
The Mullard 5-10 is a hi-fi amp. It should be quieter than, say, surface noise on a good quality 33rpm record, or background noise on a strong, well-tuned FM station heard through a good quality tuner.
Cheers,
