The contact studs on the tuner of my Ferguson 506T require cleaning, can you say the best way
to do this ? -A. E. Bellfield (Birmingham, 26).
You will have to remove the chassis from the
cabinet. Release the two left -side screws and swing
open the left side. Spring off the back of the
tuner, undo the centre 2B.A. nut and remove thé
coil disc. Clean the studs and replace.
