  • Anotaciones

  • The Philco model 49 series uses a 7-tube 2-band (BC and SW 4.2-12 MHz) chassis designed for DC mains power. The design is roughly based on that of model 118, but without rectifier tube. The series includes seven individual models with different cabinet styles.

    The early version (1934) of the model 49B table radio is a cathedral with a scalloped top. The late version (1935) is a shouldered tombstone having a shield-shaped speaker opening with three vertical and three horizontal bars through the opening.

    There are three highboys. Model 49H (1934-35) has six legs and a Y-shaped speaker opening with vertical bars. The early version of model 49D (1934) has six legs, rounded sides, and doors. The late version of 49D (1935) is very similar, but has waterfall moulding at the bottom of the main cabinet structure.

    The early version (1934) of the model 49X floor-type console has a classical design with three round pillars in front of its inclined sounding board. The late version of 49X (1934-35) is somewhat more modern in design, with three square fluted bars in front of the speaker and an emblem at the top center.

    All versions include a shadow meter (tuning aid).
