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...

Crosley Model 120 Senior Superheterodyne (Pliodynatron) Chassis Radio Service Data Sheet, June 1931 Radio-Craft - RF CafeWestinghouse's motive for dubbing the Model WR-8 the "Columnaire" is apparent when you see a photograph of it. This model also had a −R version with remote control. The remote, though, has a cable attached to it; it's not wireless like today's remote controls. There are some very nice photos of a fully restored WR−8−R version on the AntiqueRadios.com website forum. Look about half-way down the page. Near the bottom of the page is a copy of an advertisement for the Westinghouse WR−8 with a price of $193 (~$3,563 in 2022 money per the BLS Inflation Calculator).

The fundamental circuit of these receivers is the WR-5 receiver chassis and power pack shown in Data Sheet No. 29. The model WR−6 is a highboy; its circuit is the same as used in the WR−6, except as modified for tone control. The Model WR−7 is similar to the model WR−6, except as modified for an electric phonograph.

Westinghouse "Columnaire" Models WR-8 and WR-8-R (Remote Control)

Westinghouse "Columnaire" Models WR-8 and WR-8-R (Remote Control) Radio Service Data Sheet, June 1931 Radio-Craft - RF CafeModels WR−6−R and WR−7−R are the same as the respective WR−6 and WR−7 chasses, except as modified for remote control. The Model WR−8 uses the same chassis and power pack as the Model WR−6, only all electric clock and the cabinet distinguishing it as the "Columnaire;" the remote-control model being coded as the Model WR−8−R.

The "Columnaire" Model WR−8 is, except for the cabinet, the same as the Model WR−6; while the Model WR−8−R receiver chassis and power pack are almost identical with the Model WR−6−R. Leads for the synchronous electric clock are shown and, (in dots) the leads for the remote control attachment. The primary of T3 connects to the 110 V, line; the secondary output is 23 Y.

The fundamental circuit of these receivers is the WR-5 receiver chassis and power pack shown in Data Sheet No. 29. The model WR-6 is a highboy; its circuit is the same as used in the WR−6, except as modified for tone control. The Model WR−7 is similar to the Model WR−6, except as modified for an electric phonograph. Models WR−6−R and WR−7−R are the same as the respective WR−6 and WR−7 chasses, except as modified for remote control. The Model WR−8 uses the same chassis and power pack as the Model WR-6, only all electric clock and the cabinet distinguishing it as the "Columnaire;" the remote-control model being coded as the Model WR−8−R. The resistance of each individual unit appears in Data Sheet No. 29. The values of only the resistors, capacities, and chokes follow.

The phonograph attachment is shown in Fig. 2. The remote-control attachment is shown in Fig. 3. Variations in Fig. 1 are dotted.

Filament voltage (between 2 and 3 on the terminal strip A). 2.5. Power-pack output voltage (between 4 and 5 on the same strip), 250.

The color code of the push-pull A. F. transformer is as follows: T1 input, red and yellow; red with yellow tracer: Output. yellow (center-tap); and green. Transformer T2 input. red (center-tap); and blue; output, black. Power transformer PT, primary, black-with-red-tracer; black-and-red (110 volts); black (120 volts}. Secondary, 2.5 volts, brown; 5 volts. black-with-green tracer; high voltage, yellow-with-red-tracer (center-tap), and black-with-blue-tracer.

The combination model (the Model WR−7) has substantially the same receiver and power pack chassis as the Model WR-6, except as modified for the special rotary switch which makes the necessary circuit changes for the following operations: personal home recordings; radio home recordings; radio reception; phonograph operation.

Do not use the manual station selector with the chassis removed from the cabinet, unless the chassis is in a vertical position; otherwise, damage will result. Push either the "+" or the "-" button; the armature should not rise and engage the station-selector gear. Now push a station-selector button; if the armature does not rise and engage the station-selector gear, increase the tension of the spring. Next, increase the spring's tension until the armature just rises when a volume-control button is pressed; then decrease the tension until the armature just fails to rise when one of these buttons is pressed.

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.
