Re: Help needed with - Racal Dana 9081
Hi all
The project is still ongoing and after a bit more help please, quick update as follows:-
FM Loop Board
C78 burnt (47uf 16V) duff tant, R1 adjacent ok
C27 burnt (47uf 16V) duff tant, R33 & R35 read ok.
Power supply Capacitor C3 6800uf 25v duff, replaced.
The 12 volt regulator is now only putting out 1.5v, was looking to check for a short when a tant on the "Divider & Phase detector Assembly" started smoking. When I look on the layout and schematic this smoking tant doesn't appear to be present. Its a 47uf 16V tant with one leg fitted on the component side fo the board to "pin 13 of IC20" and the other leg going through the board as normal.
The attached pic shows the smoked tant in situ - has anyone else got this part present or has it been added in?, it looks factory as its the same red tant as across the rest of the board. It has one leg soldered to the track running between IC20 Pin 13 and IC23 Pin 3?
Hope someone can confirm if its meant to be there or not, mine is a Racal Dana Model 9081.
Thanks
Mark
