Crosley Model 1155, 11-Tube 4-Band Superhet
Radio Service Data Sheet
May 1936 Radio-Craft

May 1936 Radio-Craft

May 1936 Radio-Craft Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

This is another Radio Service Data Sheet like many that appeared in Radio-Craft magazine, the May 1936 edition in this case. I post this schematic and functional description of the Crosley Model 1155, 11-Tube 4-Band Superhet radio manufacturers' publications for the benefit of the many hobbyists and archivists who might be searching for such information either in a effort to restore a radio to working condition, or to collect archival information. Unfortunately, I have never been able to locate a photograph of the Crosley Model 1155 radio.

Crosley Model 1155, 11-Tube 4-Band Superhet

Crosley Model 1155, 11-Tube 4-Band Superhet, May 1936 Radio-Craft - RF Cafe("Auto-expressionator"; range, 150 kc. to 19 mc.; triple-tuned I.F.Ts.; tuning meter.)

Socket voltages are as follows, from tube to ground, using a 1,000 ohms-per-volt, meter:

*Grid 3, -5 to -30 V.

The power output is about 15.5 W., and power input 140 W. Speaker field drop, 125 V.

The I.F. alignment is accomplished by connecting the service oscillator first to the grid cap of V4, and then through a 0.02-mf. condenser to the grid cap of V2. The adjustment is made by turning the middle trimmer, never the top or bottom trimmers. Do not touch the latter.

R. F. alignment on the Blue, Red, and Green bands is accomplished with a 250 mmf, condenser connected between the service oscillator and the receiver ANT. post. A 400-ohm carbon resistor is used in place of the condenser on the Violet band. Shunt alignment frequencies are, 400, 1,700, 6,000 and 18,000 kc. Series alignment frequencies are 150, 600 and 2,500 kc.; none for Violet band.

The "auto-expressionator" is entirely automatic and needs no service, except a check to make sure the special bulbs are good.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

1996 - 2024


Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
