Default Re: Grundig TK920 3D Exploding Caps

Hi Refugee, i just read the TK820/3D manual in English, and the TK12 which is refrernced in the TK820/3D manual. There is a table that shows that each take up spook is totally not powered electrically, during play.

I can feel the reel spin with just the firction of the clutch plates, then suddenly the left spook will lock up, pressing stop, or FF/RW immediately releases the power to the clutch and it becomes free.

Thus i am convinced its Electrical, just no idea where.

I do have a TK920 schematic and few pages of text but its all in German.
