Here is the ECA (Electronic Corporation of America) Model 108 schematic and parts list as featured in a 1947 edition of Radio-Craft magazine. It had a very unique tabletop chassis design made of formable "plastic-like" Bakelite material. The front panel contains a matrix of slits for the speaker area, and the frequency strip at the top is behind a curved clear window. The speaker driver was a powerful push-pull design. As mentioned many times in the past, I post these online for the benefit of hobbyists looking for information to assist in repairing or restoring vintage communication equipment.

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 255 Radio Service Data Sheets as of April 30, 2025.
