PHILIPS B6X63A	1956	ECC85: FM Mixer ECH81: AM Mixer, FM MF-Amplifier EF89: MF-Amplifier EF85: MF-Amplifier EABC80: Detector and AF-amplifier EL84: AF Outputstage EL84: AF Outputstage EM80: Tuning-indicator EZ80: Rectifier	Wood	This is the bigger brother of the B5X63A. This one is of the true bi-ampli kind and features seperate bass and treble amplification. A lot of Philips' radio's carried the bi-ampli sign without realy being worth it because of the absence of this seperate bass and treble amplification, in this case the bi-ampli sign was no more than a marketing trick to suggest better sound performance. The sound of this set is very good with a thick bass.
