Just another note on something I may have mentioned before and have just been reminded of by a 1958 Philips L4X05T transistor set.

Many of these sets for decades used a dial cordage with a mono filament core in a woven sheath. It looks like one of the two types of nylon. Just because it is not broken does not mean that it is not going to cause one grief. There are two basic issues with it unbroken ?

Now if you happen to get solvents like, but not exclusively, Jaycar's circuit board cleaner on it, it does not like it and it tends to help it loose flexibility.. Not everything in a set likes solvents. The cordage will of course often do it of its own volition, like this Philips and also other brands using it (most). The result is total bewilderment as to why: With no obvious cause, there is a lot of slipping & not a lot of dial indicator movement.

This reminds me of my current project, a Kriesler 3k30 console. It has a few different strings from knob

shafts to indicator needles for tone,volume, and band selection. The dial chord arrangement has two

sections. one from the tuning knob shaft to the variable capacitor

wheel, and then a second string goes back out to the scale needle. I replaced the broken scale needle

line, and the knob line looked fine.

So I put it all back together after I got the set going, and the "fine " line snapped 😒

as an edit - I did give the tuning gang a good drink of contact cleaner to help release the dust and crud

settled in the fins.

Muzzery that two cord system makes the most sense. Often I come across a complex one cord set up and throw my hands in the air. I just go from the knob to the variable capacitor while ignoring the station indicator . I get that tensioner up nicely then I run a second cord for the dial which needs bugger all tension. You can't do this with all of them though.
