Question/Advice...White lightning

I have a white lightning ultra 1800, actually a friend said I could have it for $100.00 but, right now the Flash tubes will only fire very dim, by that I mean like the flint strike on a cigarette lighter. I have moved the slider up and down, no difference. Also the little green ready light is not lit. Can the flash tubes slowly be going bad, or do they either work or not? Thanks in advance. Stephen.

There is some risk here because sometimes White Lightnings are unrepairable.

What this tells me is that your master capacitors are spent. They're charging probably to about 20% of what they're supposed to. Ready light comes on when the comparator circuit reads the caps are full.... and that ain't hapnin.
