TEMPO 2020 Restoration

This excellent hybrid transceiver was designed by
Yeasu in the mid seventies, manufactured by Uniden in Japan and and sold by Henry Radio in
California. I believe that Uniden branded units were also sold in
Europe. It is a solid state design except for the 12BY7A driver and the two 6146B
finals. It has an odd hybrid frequency display with 3 led digits and vertical
drum. It has a mix of plug-in boards and hard to remove boards. Don't
restore one of these unless you have good lab equipment and skills to
restoration notes are available in PDF format with notes and pictures.
Common failures like cracking nylon sprockets and assorted geezer
electrical failures are addressed with proven repair techniques.
