DISMANTLING THE SET

Remove the four control knobs (recessed grub screws); withdraw the speaker plug from its socket on the chassis deck; from the underside of the cabinet remove the plywood strip (two countersunk head wood screws); if the two chassis fixing screws (with large metal washers) are now removed, the chassis may be withdrawn from the cabinet. When replacing, do not forget to fit the plywood strip over the chassis-fixing screws






The cabinet was cleaned and treated for woodworm The holes were then filled the inside painted with black water based paint and the outside stripped with "Nitromors" paint stripper and finished with three coats of "Danish oil" applied over a period of several days.
