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.

This 'drive-by' schematic and parts list for the Crosley Model 58TK vacuum tube radio appeared in the February 1948 issue of Radio News magazine. I refer to them as 'drive-by' because there was no description or maintenance verbiage provided. The Model 58TK is a very basic, 4-tube (not including power supply), tabletop AM tuner in a molded plastic chassis. The thumbnail at the left is from the RadioMuseum.org website - a great source for research on vintage vacuum tube radios.

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.
