Evan,
Thank you. I will look into the probe
?I may have a few parts around.?
But for the other comment, I do have the radio connected just as he showed and rf should be present in the amp. If the voltage measurement he makes between d3 and d5 is due to no or little RF then I think the irf510s are blown (most likely since i did hookup backwards) or a winding is shorted or some problem in that row of? diodes arrangement perhaps?
