Ok. one of the caps has no measurable ripple, but the other has .45 vAC.
I don't see any DC on the speaker output.
I pulled the caps and tested them. The value and ESR both looked good. I re-installed them on the board. I also removed the full wave bridge and checked it out of circuit. It's good too.
Well this has been sitting on the bench waiting for me to get to it. It has a moderately loud hum. I have recorded it. I thought 60hz hum but, i checked the full wave bridge and the 2 main power capacitors. They all checked good. Any ideas where to go from here. See the video here
That makes since. It wouldn't be the first time I got inaccurate information online.
I went ahead and pulled the part and it tested good. So, I need to go back and re-evaluate.
I agree. Thanks for the input. I'm wondering if this part had been replaced before. The board is marked with an X next to the part and the size is a little too small. The legs were bent out a little to get them through the board.
It's a DB604. According to the datasheet that's a 400V, 3A.
I'm working on an SWR Workingman's 12 combo(100 watts). I need  a full wave bridge rectifier. I have the schematic, but it doesn't show a spec for the rectifier. I checked the board and the spacing looks like .5 inches between legs. I'm thinking 5amp at 400+ volts should be enough. Any thoughts?

Thanks for the help. I've downloaded a pdf and am reviewing it.

I'm trying to locate a schematic for the Randall RG100 G3 Plus. I've looked through this section already with no luck.
