Good morning!?

Thank you!

Good morning Samuel!
? Thank you for passing this along. Unfortunately the knob from the 520 will not work here. I do appreciate you checking EBay.?

One could easily make or find someone to make a new one with a 3D printer, there are several knob designs already on 'thingyverse'

Can you put him in touch with someone who can "easily" make him one? Thanks.

Frank,
How about these knobs from a TS-140S?
 

Good afternoon!

? I appreciate everyone's effort to help me find the correct knob for this 680.

? The problem is that this stem from the pot does not protrude much past the face. As you see in the photos below most of the stem is below the face. I have knobs that are flush but there is not enough stem protruding for it to attach. I am assuming that the knob for this has a protruding stem of its own to reach the countersunk stem from the pot.?

I was thinking, since the 140S and the 680S manuals are the same... they were probably produced concurrently and share just about everything.? Also, I believe the TS-680S is a TS-140S but with the addition of 6M. But don't quote me on it.?
?
Wouldn't hurt to ask the seller to take a picture of the particular knob from a few angles.
?
Anyway, blow up the 2nd image in the ebay item I most recently sent you. Doesn't it look like it is suspended a bit above the plastic compared to the knob to it's right, thereby having a bit of a shaft extension beyond the skirt of the knob?
?
Conceptually, if all else fails, if you found a knob that did fit a 1/2 shaft, you could super glue it's shaft onto another knob's shaft to extend that shaft into the body of the TS-680S.

A bit of a MacGyver I know.

Hmm… I agree the 140 and 680
are very similar radios. Perhaps these from the 140 might work. I sent the seller a message.?
? I paid 50 bucks for the radio. … ?30 for the knobs is a hard pill to swallow … lol.?

Thanx !
Frank.?

Or someone changed the pot, possibly?

Hi Frank,

?

I just downloaded the service manual from mods.dk and the part number for that knob is K29-3080-14.

?

Why don’t you give Kenwood spare parts a call and see if they have any in stock, if you haven’t already done so? You never know your luck.

?

Otherwise, I think others have pointed to knobs on eBay or elsewhere for the TS140S which has the same knobs as it is essentially the same radio except for the extra band.

?

Good morning !?
? Thank you all for the help with the 680 knob.?
? Special shout out to Samuel for finding the 140 knobs on eBay. I messaged the seller and the knob is the one I needed for the 680.?
? It is a bit different than others so it was a great find indeed (see below)!?

73 everyone and enjoy the weekend… make some great contacts this weekend!?

Gary anyone who has a 3D printer can download all kinds of files from places like 'thingyverse', here are just a few of the knob designs available on there. Our club could make them because we have 3D printer, the cost of the filament is next to nothing, time on the printer is sendary to the time to make the design in a CAD type program, and but the cost to mail would make it prohibitive for a single knob. If you can find someone locally who has a printer, it would take minutes to print. It is also possible that one of the designs that are alredy avaiable could be modified. We have made knobs for older radios, and of course you can makes them in whatever color you fancy, but one of the grey filaments seems to be very close to the grey's used by many manufacturers.
