Good evening gentlemen : )

The Primesat PR1000 V Box that drives the jack on my C band dish failed.

No display or green LED.

The fault turned out to be O/C print to the regulator transistor that supplies the electronics on the board.

There are two supplies, one for the electronics the other to drive the jack.

The smaller set of rectifiers supplies the regulator that feeds the electronics.

The break in the printed track was close to the regulator pin, but not easy to see.

A link put things right : )

God Bless Spiff

Hallo Dreambox1959 on this sunny day : )

Thank you very much for the circuit that is great to have.

I had assumed the other regulator was for the motor volts but not so, when I think about it there is little need for the voltage to the jacks to be stabilised : )

I replaced the output connecters with mounted chock blocks at the same time as one was falling apart.

The same connecters failed on the other one I have for KU Band.

I think I posted the mode online some time ago ?

Timer for a run it the warm sunshine : )

God Bless
