My first project, yay!
So, I have this old tube tester. I'm guessing from around 1949 (http://www.mzentertainment.com/studio_workshop_test_equipment_jackson_model_103_d ynamic_tube_tester.html) or so.
I'm hoping its a relatively simple project to start off with.
Its in pretty good condition as it is, and it even works.
I've made a short video asking about it: http://www.youtube.com/watch?v=Im7wcwQQCVA
The only problem it seems to have are the scrolls with all the information on them: http://www.youtube.com/watch?v=r0nj4FstzGM
Well, I think I've made my first mistake tonight.
I stared at a big wax cap for a while and couldn't find any information written on it. I stripped off the first layer of wax (disgusting) and found the information down there.
Its a 400 volt cap, but I don't know where the capacitance is. I might have stripped that part of it off...
I did find where someone else was restoring one of these (http://www.mzentertainment.com/pics/test_equipment/jackson_model_103_tube_tester/jackson_model_103_tube_tester_project2.jpg) and the cap they replaced this with just says "104k 630 v" on it.
I'm assuming this means 104K uF at 630 volts?
So, any input on that or the scrolls is appreciated.
