The Philco 38-665B is a nine tube, four-band, tombstone radio that was manufactured in 1938.  Only the 38-670B surpassed it, in tube count and price, in the manufacturer's 1938 table model line up.  The 38-665B was housed in the same styled cabinet that was used by the next model down, the 38-643B.  The chassis was identical to that of the 37-665B from the previous year.
    Personally, I prefer this radio's flamboyant and stylish cabinet to that of the 38-670B, with it's rather boxy and stodgy looking cabinet, or any other Philco table model radio.  Unfortunately, despite the fact that Philcos are just about one of the most abundant antique radios to be found today, this particular model is one of the most elusive to find.  This set is the only one I've ever seen other than what is illustrated in various antique radio resource books.  After the total rebuilding and alignment of this set's electronics, the reception is very strong and sharp and the audio sounds great with a nice ambient sound.  This set was purchased, in May of 2005, from an auction on Ebay.
