Changing stations late Friday evening and the dial started to spin- but the needle did not - and I got stuck on something in between KPFA and KALW...
Took off the cover - and saw that one of the THREE dial threads was broken - but in that there are three - the tuning wheel (attached to the variable capacitor) was still connected to the needle - so I gently tuned in 91.7 - KALW.
Saturday I took the unit out to repair - what a project:
Removed guard- done Friday - now take off the knobs,
Outer Glass faceplate-
Inner glass face-plate - well - not quite off - but disconnected enough to tip forward so that I could get in to replace the thread-
Thankfully I had a second to make sure I got it correct-
I know - I should have taken pictures - if only to share
All back in business again but the dial / needle /station alignment is not quite right - a smidge to the left...
next time I'll do better-
To get KPFA over the air.

You did put a new string on,correct?

A recent purchase is a 65-9ish MR71. Any warning signs prior to?
I CAREFULLY/slowly tune stations in. While the "feel" is still smooth and quiet, I'm aware anything can fail in a 50 year old tuner.
I couldn't imagine trying to restring the dial. Seems like an excercise in patience and fussing.
Something that would have to be done by a shop for me.
It is not a job for the faint-of-heart, that I can attest to-
here are some pictures of the unit operating with the new red thread-
No there was no warning sign - just broke-
I do have a good tech in the area and would have gone to him- but wanted to see if I could get it done myself-
the last picture shows the 'dial indicator needle electrification in detail-
Oh my....it looks complex if you don't have a clue(myself)
The pics are a reminder what I did in the early 80's. I was that copier repair guy who would stroll into your office to fix that damn copier which jammed all the time!
Now and then I would restring the lamp assembly which scans the original. Talk about an electro mechanical mess!
Nowadays, I avoid tasks that involve more than use of a screwdriver.
