Amplifier Discussion / SWR Workingman's 12 combo- Hummmmmm
« on: January 05, 2022, 05:04:32 PM »
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

Amplifier Discussion / SWR Workingman's 12 combo - Full wave Bridge spec
« on: December 10, 2021, 12:10:06 PM »
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?
