I had a broken 1571 on which I located the problem to the powersupply.

The PSU is relatively easy to refurbish with new caps and so forth, but I wanted to try out a switching powersupply i had.

The new powersupply is a MeanWell PT-65A and is rated 5VDC/7A and 12VDC/3,2A. It also has a -5VDC/0.7A output which was not used. This specific model was on a €4 sale at a electronics distributor and the current ratings were good, hence the selection.

 

WARNING! LETHAL VOLTAGES ARE PRESENT ON THE POWERSUPPLY.

A very tight fit, I had to make a cut on the left side.
The PCB is mounted on spacers and the cables were crimped.
