Build it yourself ! The OSC4.7 kit includes the pc board, transformer, wires, components to populate the board and IC's including the preprogrammed microcontroller. You can source your own crt and build your own enclosure. Many small relatively low voltage crts will work if similar to the DG7/6 or DG7-12C types. This is a really challenging DIY project but can be very rewarding to the builder in building it accurately and adjusting & tweaking the controls to optimize the display.
A fully assembled clock with homemade plexiglass case including the 1/4" thick base and 1/8" thick shroud or dust cover. Uses the 3" diameter by 7" long DG7/6 crt. Easy to set for 120VAC (standard U.S.) or 240VAC (some other countries) and automatically sets for 60HZ or 50HZ.
The deluxe edition ! Fully assembled clock in homemade case built with choice of DG7/6 or the DG7-12C (3" diameter with very nice resolution, 8" long) with gold-plated electrodes. Gold pin sockets for the IC's and high quality components. Will also come with free upgrades to new firmware in the future !
