#RCA VICTOR RADIO CONVERSION KIT FULL#
Do not attempt alignment without full instructions. I had to rely on the wiring and the band switch contacts to pick the right coils and caps to adjust. The Sams Photofact helps a great deal but leaves out the location for a couple of the coils. It is a bit more complex than the Transoceanic. The voltages stabilized after cleaning the tube and socket contacts and the set began playing.Īligning this set is not for the faint of heart. Wiggling a couple of the tubes in the socket confirmed the suspicion. Suspected dirty tube filament contacts creating high resistance in the filament series line. Found the filament voltage going too high and somewhat unstable despite relatively low voltage input. As I typically do with these sets, I powered it up on DC from a regulated high voltage supply while monitoring the filament voltage. I cleaned all the controls including the bandswitch with deoxit. This set does have the 50A1 tube indicating it was a later model improvement. The version in Sams does not include the filament-type ballast tube 50A1.

The tube complement is the same as found in the typical Transoceanic with 3V4 audio output, 1U5 detector/AVC/ audio preamp, two 1U4 for RF and IF amplifiers, and the expensive 1L6 converter.Schematic, alignment and other information can be found in Sams Photofact 248-14. Like the Transoceanics, the RCA Strato-World is quite sensitive for shortwave listening with just the built-in telescoping whip antenna if the radio is working well. The latter 4 are called spread bands, each covering a relatively narrow section of the short-waves thus eliminating the need for a separate "bandspread" function.

Like the Zeniths, it covers AM broadcast, two wide shortwave bands, and the 16, 19, 25, and 31 meter international "world-band" shortwave bands.

The RCA model 7-BX-10 Strato-World is a Zenith Transoceanic "clone" that is rather well-made.
