The (newest, raster style)
OSC7.8 Oscilloscope clock kit
The OSC7.8 kit is a professionally made pc board
and the components to populate it, including the ICs and the
preprogrammed ESP32 module written with my firmware and the toroidal
transformer. I supply the instructions for assembly
and a parts list (in digital format) with the board and components.

I have some crts
available at varying
prices according to scarcity. Some CRT types that I have used with this
board are: DG7-6, 2AP1, 2BP1, 6Lo1i, 3RP1 and 3BP1.

The OSC7.8 board (low voltage version) connects to U.S.(120VAC) or other (240VAC), and it
will drive many relatively low-voltage crts such as 2BP1, 2AP1, DG7-6,
6Lo1i
and others.

An
unsolicited testimonial:
"Howard,
Wanted to send you a few pictures of the evolving project. Reduced
Rfilament to 1ohm to realize a ~6.2VAC heater voltage. Focus and
intensity of the CRT looks good. Energized the native oscilloscope
circuit to illuminate the 'scope display grid. Very happy with how this
is coming together. I wanted to thank you for all your effort and great
execution on this. Very impressive that you single handedly integrated
high voltage electronics, consumer-grade AC power conversion circuits,
analog amp design, data converters, PIC programming, user experience
design using a 3 button interface, submicron GPS chipset programming
and system integration all at the same time. Not to mention being
available to answer questions during the build! Let me know if there's
anything I can do to help with your future goals, projects, and
endeavors. Brian"
