Classic UK Minitrix Models  -  Lights
Curing the Flicker
Fit the light bulbs.  Make sure the two contact and retaining clips are clean.  Alos clean the outside of the grain of wheat bulb and lightly emery the metal contact at the end of the bulb.
This is where the strips fit - but I find that over the years, they no longer provide adequate spring, and the contact is poor.
So get a small screwdriver above the place where the bulb fits and press down...
Making a depression in the middle of the strip.  Ensure that the tabs on either side are pressed against the chassis side, and that they have not been bent outwards as you pressed down with the screwdriver.
Put the bulb into place, and fit the clip.  The bulb is now firmly located and any flicker caused by poor contact will have been eliminated.
