Notes This was one of the best AC Plano type radio sets made by Philips India. It had a separate bass and treble amplification control.Inspite of using only 1X EL84 and 2X EBC81 the sound Quality was just Superb.The Low frquency response was from the speaker AD3800X=5 Ohms and the High Frequency response from the speaker AD3700AM- 800 Ohms speaker connected to the primary of the output transformer through capacitors. Two Separate Gang Condensers were used. One with special shaped vanes for the band spread bands and the other for the rest 3-bands. Both the Gang conensers were coupled by thread. It also had a Band Width Control for removing interference from nearby stations.
