 Passive Devices Inc., has available a line of replacement pads (PDP) and both forward (PDE) and return(PDER) replacement equalizers to fit all 550, 750 and 860/870MHz versions of Magnavox/Phillips, Jerrold/General Instrument and Scientific Atlanta amplifiers and line extenders. All return equalizers are 40MHz versions. Equalizers are chosen according to the dB loss, at the highest frequency used, of the cable preceding the amplifier. The equalizer insertion loss at the highest frequency is approximately 1dB. PDE equalizer deltas follow original manufacturer's specifications.
