The 4th version of the Philco 16B was introduced in January, 1935. The cabinet is the form of a shouldered tombstone with a somewhat butterfly-shaped grill. It uses the code 125 late chassis.
The model 16 series were high-end multi-band 11-tube radios sold by Philco for about 2 years spanning the 1933, 1934, and 1935 model years. There were two basic versions of the chassis referred to as 'early' and 'late'. Both the early and late chassis used a type 80 rectifier tube for the 16B table models, and a 5Z3 rectifier for the console models. Both chassis included dual IF-amp stages and a shadow meter (tuning aid). Both chassis were available in a version for 25-40 Hz power, and these chassis are marked as "16A" (where the -A suffix is a chassis suffix, not to be confused with the cabinet suffix on the main model number).
The early chassis used in 1933-34 included a QAVC ("quiet automatic volume control") squelch circuit to silence noise between stations. Squelch was implemented with a dedicated type 78 tube, and controlled with an on/off switch on the side and a potentiometer on the back to adjust the squelch level. The early chassis received five bands: 520-1500 kHz, 1.5-4.0 MHz, 3.2-6.0 MHz, 5.8-12.0 MHz and 11.0-23.0 MHz.
The late chassis (1934-35) eliminated the QAVC feature and repurposed its 78 tube to be an RF amplifier stage in the front end, thus maintaining the 11-tube count. The switch on the side of the cabinet was used as a bass-boost control called "Loudness". The late chassis covered a similar tuning range, but with only four bands: 550-1500 KHz, 1.5-4.1 MHz, 4.1-10.0 MHz, and 10.0-22.5 MHz.
The chassis codes are as follows:
Code 121: early chassis with 80
Code 122: early chassis with 5Z3
Code 123: unknown
Code 125: late chassis with 80
Code 126: late chassis with 5Z3
Code 127: unknown
There were fifteen versions of model 16 in different cabinet styles over the three-model-year span:
Four versions of the 16B cathedral/tombstone,
Three versions of the 16L lowboy console,
Four versions of the 16X floor-type console,
Three versions of the 16RX chairside,
A special 16CPX chairside.
Stein "Cathedral & Tombstone Radios" lists only 2 bands.
