The weak sound is fixed. The bad diode on the board was not defect but it was replaced.
DCC-Life was good, until i changed the belts and the pinch-rollers. My beloved 951 stopped working. Moment A is working, moment B not. Then i took a good look at al my 951 pinch rollers i had. And this is what i found:
The little ones where in my first player (The one that said on 33 tapes ‘clean head’), the other white ones are ‘techkey’, the black ones are original ons, but they are far gone.
So, i switched the pinch rollers to the black ones again, and the player did read side A (and played)! But as soon as we have to flip to side B, the player stops and when i try to get the tape out by pushing ‘Open’ key, the display tells me ‘BLOCKED’, i cannot get side B to work.
I am now so far that i dont know anymore what the Standard pinch rollers for a 951 are, same goes for the belts.
Now i bring both players to a company specialized in reparing old vintage audio with lots of experience on the DCC.
Lets hope we can get one decent reliable 951 out of the two units. Thumbs crossed!
