It is a 1985 vintage 3 tube front projector. It has a slide out board
with 20+ so called convergence controls on it. Under the best circumstances the convergence will be marginal at best. Do not forget those tubes used an optical Gel between the lens and crt face for cooling. Most of those I saw 10 or so years ago the gel was going bad and the convergence and image quality could not be acheived without replacement of the entire crt assembly. |
