I am busy replacing parts on a '68 40W/c Grundig integrated amplifier. Replacing capacitors were easy enough as polarity is easy to get right, until I came to the hear damaged bridge rectifier. The replacement rectifier I want to use has the + and - markings indicated diagonally.
The damaged rectifier has its 4 pins coming from the rear with + and - to the left and the other 2 pins grouped on the right rear.
The circuit board is not marked and and I'm not sure which of the rectifier's + and - pins goes where.
The only 'clue' I have is looking at the old rectifier's + and - pins on the left. If one flips the old item (which has fallen apart), there are + and - markings on the underside of the case. The nearest marking to pair of pins on the left is - and straight ahead on the same side is a +.
Since the replacement rectifier's pins are arranged diagonally and clearly marked + and -, I'm not sure how get the replacement's polarity correctly orientated on the board.
Any ideas how to determine which goes where? There are several capacitors around this part. Can one measure from a capacitor's - to find out where - is for the rectifier?
The only other 'clue' I can offer is looking at the fallen-apart original rectifier's innards, the lower pin touches a metal clip covering the other bits inside.
mafioso
