Ok so I was putting my parts out on the work bench doing a dry run layout and it hit me.....Not only are carbon resistors old school but I think the design I am following is old and out dated.
Oh I was lying out parts for my rectifier/doubler board. It called for 100 ohm 2 watt carbon resistors. So I was thinking why not use 10W wire wound resistors? So then I got to thinking why 100 ohm? Was that just a convient readily available size value when the design was drawn up or was it just what the guy had a lot of in his junk box? If I increase the ohms of resistance wont I also improve regulation of the power in the rectifier board?
So know I am thinking maybe something in the 5-10 watt range in a wire wound resistors might be better? So where is the sweet spot? Is it 200 ohms, 500ohms 1kohm, 100kohm. I guessing that size is going to be a limiting factor. Wire wound resistors get large in a hurry. So anyone played around with resistor values in the rectifier section? I am definitely not going to use carbon resistors and definitely no 2watt ones either.
Am I spinning my wheels over nothing????
