I pulled the cover plate off and looked. It is very simple inside. The DC is from the receiver is blocked by a cap and there is an inducter to take DC off the line. The amp looks to be maybe some kind of op-amp that drives a single transistor. I can't read the part numbers on any of the active components. We know it is a line extender so the 10dB guess is reasonable Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
