Annotazioni The Philco model 200X (1934-35) was one of the industry's first high fidelity radios. The ten-tube single band chassis has variable IF bandwidth to trade off selectivity versus fidelity, controlled by a three-gang potentiometer to adjust the Q of the two of the IF transformers and the gain of the mixer stage. Unlike most radios of its day, which were restricted to about 4 kHz of audio bandwidth, the 200X has 7.5 kHz of bandwidth at its maximum fidelity setting. The circuit includes a 10 kHz audio filter to remove the high pitched heterodyne that could be caused by the carrier of an adjacent channel. The chassis has a shadow meter (tuning aid) with its own dedicated control tube (unlike other Philco designs where the shadow meter simply indicates B+ current to the RF and/or IF stages). The push-pull output stage, with one 42 driver tube and two 42 output tubes, delivers 15 watts of undistorted output.

The cabinet is a floor-type console with inclined sounding board.

Philco also introduced another high fidelity model in 1934 - the 201X. It was similar to model 200X but had two bands (BC + SW).
