Hello all.
I seem to have become a lover of all things valve related in general. I did order a televisor from Mindsets, but I believe due to the semiconductor shortage it may not arrive until next year!
Anyway I have started a project with the aim to decode NBTV pictures, even if only from audio files from the pc meant for the Mindset televisor.
The project is valve based up to now, has a 5FP7 CRT with a valved EHT generator and separate valve line time base, it is a slow ongoing project and I am sure that from time to time I will need to ask for help. The next stage I need to build is the frame timebase and see if the Miller Transitron will work down to 12.5 Hz or if I need to use a Thyratron and Pentode constant current source. Not sure if at these frequencies I can get a suitable swing in deflection, but time will tell.
Enough for now.
Cheers
Adrian
