|Shape||Tablemodel, low profile (big size).|

|Notes||The Philco model 610 series uses a 5-tube 3-band (BC, 2.3-2.5 MHz, and 5.7 - 18 MHz) chassis. There are four distinct models with different cabinet styles.
Model 610B (1935-36) is a shouldered tombstone. Model 610F (1935-36) is a floor-type console with a tulip design for the speaker opening. Model 610PF (1935-36) is a radio-phonograph in a similar console cabinet as 610F, but with a roughly rectangular speaker opening with three vertical bars, and slightly taller than 610F to accommodate the phonograph under the top cover. Model 610T (1936) is a table radio with a round left side, with a speaker opening that combines a round lower half with several horizontal bars in the upper half, somewhat resembling a small Greek 'sigma.'
The 37-610 series (1936-37) and 38-610 series (1937-38) were similar in electrical design to the 610 series, but with updated tube types.
The model 611 series is similar to the 610 series, but with AC/DC power supply instead of AC-only.
