Re: My first foray into Old model TV repairs. Ferguson 991T.
Agree. I did mention earlier that it is a fringe model designed to give a picture under very poor conditions such as operation in a very low signal area or a location where excessive interference [motor car ignition or heavy industry] would probably unlock the timebases under severe conditions. It has probably been aligned for gain rather than definition. reducing the bandwidth can eliminate the majority of fine grain [noise] a common feature of fringe area viewing. J.
Realignment is dodgy unless you have a very accurate signal generator paired with a frequency counter. I would be tempted to leave it alone unless you have the equipment.
