      I hope it's not ballasts. It took me a couple of hours to properly
      replace two of them a few years ago. The machine is simple (if it's
      like mine), but you still have to be careful and slow as you take it
      apart, or you could disconnect wires inadvertently. The more nimble
      your fingers, the better.

        Hi Scott

        The problem with ballasts is that if they start going on you, you likely
        need to replace the whole lot of them at once, as they too, like the
        bulbs, have an age limit.

        I was having a problem a long while back with my Orbital VIII. They were
        going like popcorn and worse, no longer made. A&V was pulling them from
        trade-ins and selling them for $$35-50 a pop, used, as is. I finally got
        tired of that and bit the bullet and rewired the whole board with the
        Work Horse 5s. Not exactly something I ever want to do again though.
        Amazingly, when I put the board back in, everything lit up like it was
        supposed to.

          I searched google with every variation of terms with that part number and could only find suppliers in Europe.

          The bulbs actually look pretty good. No discoloration to speak of. All the lights come on at the same time and almost instantly, so hopefully that means the ballasts are OK.

            I checked the link you sent and couldn't find the bulb there. They did have a 15 watt "black light" bulb that would fit and according to the graph emits light in the right range. I wonder if 15w vs. 20w would make a difference?

                Order from Europe. I have a side business where I am constantly ordering
                from European countries: Spain, Italy, Poland, Germany, Ireland,
                Hungary, Finland, Latvia, etc. (I avoid Russia!!!). Never had a problem
                except for the transit wait.
