The Thylacine higher line rate monitor
Posted: Thu Aug 03, 2017 7:25 pm
I have named this Monitor Build the Thylacine big brother to the Devil as the Tasmanian devil was to its bigger competitor the Tasmanian Tiger The Thylacine so in this case line rates touch under or over 100 lines .....well thats the plan ... any way i have the Devil working so just need a higher line rate monitor for the flying spot scanner camera build no use having it and no way to view it .
The problem with the Devil as Steve pointed out for any higher line rate is raster spot spot size and over lapping lines with the smaller electrostatic tube which i did notice on the 120 line tests .
So this is where i am at
I finished off the variable EHT and another inverter for the focus positive and working on the first sawtooth oscillator it will pretty much work off a dual 12 volt supply ,one circuit at a time and i know what works so using circuits i have used before here /
Everything working so far which is good ,i will fire it up again when i have at least a deflection amplifier working should be around the weekend if not both.
