Stella ST106A drive cords - UK Vintage Radio Repair and Restoration Discussion Forum

Hi. I am restoring a Stella ST106A radio, but I am having difficulty in re-assembling the two drive cords (wire). They do not seem to go back once winding them on the drum, and the longer wire does not reach the spring hook. All that I have is the Philips manuals, and this differs by having two guide pulleys whilst the Stella has one. Can anyone assist, please?
Many thanks
Mike

Hope this is OK but since the tuner cord layout for the Stella ST106A is not included in the above download for the RTS book, I have scanned it from the service manual. It's been reduced in size so hope it comes out OK.

Hi Dave.
Many thanks for your reply. I thought that it was different from the Philips radios, as the Stella only has one cord pulley.
Cheers

Hi Dave. Is the longer cord 2 turns around the drive drum (clockwise) or two and a half turns?
Cheers

If I'm looking at it correctly the longer section is twice round from the bottom where it meets the pulley and then a quarter or so to reach into the pulley hook. It might be easier if you enlarge the image either on screen or as a print out.

Hi Dave. It does not copy from the image. All that I know of is that the small cable starts at 4 o'clock position, and the larger length at 12 o'clock.
Cheers

Should have added this text about the pointer drive earlier.

POINTER DRIVE
Make up the cables as indicated in Fig. 1.
Turn gang to maximum capacitance.
Insert the end of the shorter cable into the top slot in the moulded drum. Wind on one turn anti-clockwise, hook the end of the cable on to the spring, and hook the spring to any convenient anchorage point.
Insert the end of the longer cable into the slot at 4 o'clock on the drum. Wind on two turns clockwise, pass the end of the cable round the pulley, and hook the spring on to it.
Fit the pointer by winding two turns of cable round each half of the base of it.

When I get a bit more time I'll scan the page with this info, it also has instructions for 'Trimming' and 'Capacitor Drive Replacement'.
