WebMay 2, 2024 · A guitar power amp needs an input of 20 dBm to achieve an output of 25 dBW. What is the gain of the amplifier in dB? First, it is necessary to convert the power readings so that they share the same reference unit. Because dBm represents a reference 30 dB smaller than the dBW reference, just subtract 30 dB to compensate. http://www.hifi-amplifiers.com/en/original-cd-player-power-filter-socket-c-95/original-opa3a-300b-vacuum-tube-amplifier-hifi-headphone-balance-output-amp-p-5238.html scuba tank information https://druidamusic.com
