FADA "Special" on eBay

The following announcement was posted in the September 1930 edition of Radio−Craft magazine regarding Radio Data Service Sheets:

"We are pleased to announce that RADIO−CRAFT has taken over the subscription list of 'RADIO SERVICE,' formerly published in Dallas, Texas. All subscribers of record to RADIO SERVICE will receive RADIO−CRAFT until the expiration of their subscriptions."

Prior to that, the "Radio Service" company must have contracted with Radio−Craft to provide the information. This one in particular features the Fada Radio and Electric Company of Long Island, New York, models 265−A and 475−A. Thanks to the nomenclature plate on the "7" listed on eBay, we see that FADA stands for F.A.D. Andrea, Inc. We still don't know what the initials stand for, though. I had the Wayback Machine™ capture a copy of the listing so that the photos will be available in perpetuity. A magazine ad for the FADA "Special" on the RadioMuseum website shows a price of $95, which in 2023 money is the equivalent of  $1,709 - yow!

FADA "Special" Model 265−A and FADA "7" Model 475−A

FADA "Special" Model 265-A and FADA "7" Model 475-A Radio Service Data Sheet, September 1930 Radio-Craft - RF CafeThe following is the procedure to be followed for neutralizing the Fada "Model 265-A" battery set: the neutralizing condensers C7, CS, C9 are located from left to right in the set. Balance V3, V2, V1, in the same order, using a tube with an open filament. Adjust on a wavelength between 250 and 300 meters. To neutralize this receiver it is recommended that a type '01A tube be used in the detector position, V4; replacing, when balanced, with a type '00A tube. The compensating condenser C3A is located at the right of the third tuning condenser and is adjusted with a long screwdriver. In the Fada Model 475-A" receiver, C7 is accessible through the left hole (facing front of set) in terminal board in first can; and the second neutralizing condenser C8 through the right hole. Condenser C9 is reached through the right-hand hole in the second can; and C10, through the right-hand hole in the third can. Each of these condensers is numbered according to the stage it balances. It is recommended that headphones be used to obtain a null point when balancing the receiver. Tune for a strong signal on a wavelength of 250 to 300 meters, when balancing this set, using the loop for signal pick-up. The input circuit compensator C1A is the thumb screw marked "antenna adjuster" on the terminal board in the first can. Condensers C2A, C3A and C4A are accessible through holes in their respective shield cans. Wavelength compensation in the various tuned stages is obtained by tuning to a strong local station (using the loop) on a wavelength between 250 and 300 meters. After obtaining the loudest signal at a single point, remove the loop plugs and connect an aerial and ground to the set. Without moving left-hand dial, turn antenna adjuster screw to left or right to point of maximum signal.

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.

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...
