Got a receiver where the dial string slips just a hair when the receiver is first turned on. I can turn the dial in the opposite direction just a bit and then reverse and all is good for the rest of the day.
There used to be a dial string dressing that would correct this, going back to the '60. Does anyone make something like it today or does anyone have an idea for a substitute. I do not want to try to tighten the cord as it seems fine as is and has subjectively the same tension as another receiver of the same brand that uses the same layout, etc and does not slip.

I would add tension to the spring at the tuning wheel on the variable capacitor if cleaning does not work. Some tuning wheels (pulleys) have a second clip to add additional spring tension. If a second clip on your pulley does not exist, add a second knot over the existing knot on the spring. Do not untie the original knot as the string is not long enough to re-tie.
Violin bow rosin works great. I have had success with it.
Good luck
Time to hit an instrument shop, excuse to hit it and maybe get a harmonica as since with the number fingers my goal of learning the guitar is deadended.

Hi,
Richard Modafferi used ski wax for this purpose on my MR78. I always wondered if violin bow rosin would work in this application since it helps the bow "grab" the strings. Might not be too easy to apply in situ though.

Thank you for the ideas. Guess time to hit the sports shop and get the wax and at the same time pick up some pucks. I used them under equipment and speakers.

The first thing I would try is cleaning the pulley track the string rides in. A Q-tip lightly moistened with alcohol should work. Don't saturate the string though.
Secondly, I'd (again lightly) lube the bearings of the pulleys.
Have you popped the lid to determine that it's actually the string slipping? As stellavox suggested, it might be something else. I'm not sure what else it could be, but have a look.
Good luck
Yes, have had it opened and confirmed there is nothing interfering with the system and the string pulley, etc as well as the dial pointer track is clean and smooth. When opened, I can see the slight slippage and when I reverse the direction it catches and then works okay. I have dry wiped the shaft where the string wraps around but no improvement. it originates usually over time as the string wears and becomes smoother as well as a very slight stretch. The cord is not worn, just polished.
Back in the olden days this was not uncommon and why they had the dressing.

Brian,
I don't understand your situation. It sounds like another mechanical problem - is some part (lever) of the on-off switch mechanism touching the dial mechanism somehow? May not be cord slippage problem.
