Restoration Notes

This nice black and white television was given to me at a VRPS meet for free. The reddish mahogany cabinet was in superb shape and needed little attention. When the TV was first fired up, no picture came up on the screen so the electronics needed work. The repair process is covered in the restoration notes.

Restoration Notes

This wonderful tabletop black and white television is enclosed in a beautiful all-bakelite brown cabinet. These sets were popular in the late forties and featured a transformerless design with the tube filaments wired in series like christmas lights, which helped lighten the weight. However, if a tube burned out then the effects could be dramatic. Below are scans from the SAMS Photofacts for the GE 805 television for anyone who might need the information:

    These Mallory UHF tuners are easily identifiable by their notable reddish brown cabinets and classic appearances. Moreover, this tuner was a very popular device for converting the UHF channels (14 to 83) to channel 5 or 6 for the VHF band on the television.

    Rebuild Notes

    The Pilot TV-37 was one of the first economy televisions that sold for under $100 at a time when most televisions cost more. The Pilot used a three-inch 3KP4 CRT with white phosphor, which is considered very rare and difficult to find. This Pilot first came in my possession in 2005 as a mere chassis with a dead 3KP4 CRT and no tubes. This Pilot was rebuilt almost completely, and the cabinet was created using thick plexiglass.

    Solid-state, AC

    This Sony is a neat black and white video camera with a 2/3" vidicon camera tube. One nice feature about this camera is that it provides either composite NTSC video or RF output on channel 3.

    Solid-state, AC or Battery

    I got this black and white portable Sony television for free because it had some reception problems. Nevertheless, it was one of the earliest portable transistor televisions at the time.

    Solid-state, AC or Battery

    This TMK is one of numerous black and white portable televisions that were popular during the eighties.

    Tote-Vision UT-5501 TelevisionTote-Vision UT-5501
    September 1983

    Solid-state, 12VDC or Battery

    This television is just another one of the many black and white portable televisions made in the eighties. I implanted a RF modulator in this television so I could feed composite video and audio to it. Although it is incredibly inefficient to modulate video into RF then have the TV demodulate the RF back to video, it worked well for some of my video experiments.
