Collins 30L-1 I will be rebuilding the Rectifier Board

2012_0717Collins30L10008

Old Rectifier board, note the Diodes that have been replaced in the past, I will be cleaning the old board by removing the old components  and replacing them with new and also better values, so that they can withstand the power draw. The components are best removed by clipping them off and then removing the leads after. Once done you will have to drill the holes for the diodes as the new leads are larger then the original holes in the board.
