Hi All: With the "shelter in place" going on I have a lot of time to work on the projects that have been "staring at me"
I have a Sperry "evaluation" clock which uses the sp-151 + sp-232 displays. I acquired it in 2015, and it has never lit up as long as I have had it. I went and replaced capacitors, transistors, and resistors (I think on the resistors), with no luck. I have also tried swapping the MM5314 chip with a working pull. Still nothing. Is it possible that the displays have merely reached the end of their useful life and are just no good? I have the manuals for the clock and am at a loss as to where to go from here. Can anyone help me ? I would love to get it working, as there is a special place in my heart for old electronics (my XYL, and Accountant both HATE my Heathkit GC-1195 With the chime kit that I restored the case and converted the display to LED's) Anyone have any ideas where I should start looking for problems? de Howard, N9KTW -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
