Thank you,

Steve,
I did a bit of research for you on this one. Sparton made two different 5006 models. Need to check the actual circuit first to verify whatcha got.
Model 5006X, 25TK10A chassis uses PC7007 flyback. You can verify this by finding a 1X2 H.V. rectifier tube in the cage. See attached picture with schmatic. This fly has a 4th tap that goes directly to the anode of the damper tube! That should sub to a Merit HVO-10
Model 5006, 23TD10 chassis uses a PB40216 flyback. You verify this one by finding a 1B3 H.V. recitifier tube in the cage. Schematic also attached. This fly does NOT have a 4th tap going directly to the anode of the damper tube! This would be a Merit HVO3, or Thordarson FLY 1
Look forward to some pics when you get'r going.
Tom
