Grundig TK27 No Record
There is no erase signal at the erase head. The record red button is very hard to press.
So I removed the switch bank at the lower right of the case, under a metal shield. I cleaned all the contacts with light emery paper, and noticed some important clues.
1) The tight button push is because there is some of the old crappy metal in the sliding part of the switch that has deteriorated, and some of it has fallen off. but it does move, though sticky and I will free it up.
2) I have noticed one switch does not move the contacts when the switch is pushed in or out. See photos with yellow circle around it. You can see the switch is pushed in, but the centre spring in the contact block is not moving. This can't be good !
I will try to get this switch to open and close with the pushing of the button. With the unit on its side, speaker up, the switch is at the top of the block, facing the motor.
