      Dez's 25" Starwars vector monitor project

      edit: 11 June 2011 PROJECT SUCCESSFUL AND WORKING!

      . . . . . . . . . . . . . . . . . . . .

      Hi guys

      This is about making Starwars 25" monitors from a NEC 25" TV, IE the one in the wooden box - All you TV collectors / hoarders like me, know the TV I mean

      I spoke to Jomac the other day, he was kind enough to read to me the neck pinouts for the NEC 25"

      I was looking at the pinouts of the Amplifone / Rauland monitor as he read them to me from his book - Guess what - they were identical to each other

      For a TV to be usable as a Vector monitor, the following must be compatible
      1. Neck Size
      2. Neck Pinout
      3. Neck pin Pattern and size
      4. Deflection angle
      5. HV value
      6. Yoke resistance and Impedance
      7. Heater Voltage

      Ok, so:
      They are identical pinouts

      Now the Yoke on a 25" Amplifone is different to the 19" Amplifone.
      The 25" SW used the WG6100 Yoke like this below, and is suited to 100 degree deflection angle tubes

      Click enlarge

      The 19" one looks like this by the way

      The 19" Amplifone YOKE is a 90 degree, so the yoke is not really compatible with the TV will be trying to use here.

      So back to our list
      1. Neck Size (Check) ie Yes
      2. Neck Pinout (Check)
      3. Neck pin Pattern and size (Check)
      4. Deflection angle (Check - 100 degree)
      5. HV value (Unknown as yet)
      6. Yoke resistance and Impedance (Must have original WG 6100 Yoke) - Sorry
      7. Heater Voltage (Unknown as yet)

      So what I intend to do is actually prove this can be done

      I will document the path I take until we all see it working

      Items needed
      A. Working 25" Starwars Machine (Check)
      B. Spare WG 6100 Deflection Yoke (Check)
      C. NEC 25" TV's (Check)
      D. HV Probe and Scope (Check)
      E. Rings and wedges to suit (Check)

      Those who know me will also know I take forever, but get there eventually. So jump onboard, but be patient

      Input is welcome

      so then if i aint wrong it just a matter of replacing the yoke thats currently on nec tv tube with the wells gardner one you have and resetting convergance and purity... cool to easy.
      What about the heater voltage on the nec tube how do you determine value and if its compatible?

      You still need a WG6100 yoke though.

      I have a few WG6100 yokes, so I may sacrifice one to try and have them manufactured locally eventually

      Every yoke cost $90 US or more, so are getting harder to get

      I wonder if anyone on AA has one?

      It would be nice to rewire the one in the TV, so that might be the goal actually if possible
