Default Re: Grundig TK27 - Low audio output

As soon as I read that the record button was hard to press I knew what the problem was. It's that spacer, lower middle of your first photo. As you have noticed, it swells up and disintegrates. That stops the slider from moving and operating the switch contacts. There are two spacers, one either side of the switch mechanism.

I've got two TK27s and both had this problem. On one machine one spacer had fallen to bits while the other was perfect, the one in the pic, but on the second machine both were affected.

The only option is to make new ones. I used some epoxy putty which I shaped roughly by hand, then left it to harden and filed to size and shape. Don't know what facilities you have, but I don't see why one couldn't be made with a 3D printer.

They are a royal pain to get out and just as bad to get a replacement in and all the screws tightened. Hope you manage to come up with something.
