I need to replace several --1/2 and 2W-- resistors in my 30 (?) year old Dynaco high powered amp. The amp has been professionally worked on a couple of times in the past, and some of these resistors show significant heat and trace repair around their mounts. I'd guess a couple have also been replaced with resistors that are physically considerably bigger than the originals.
1. Should I be concerned over what type of resistor to use: carbon, wire wound, metal oxide.....?
2. Would it be a good, or bad, idea to increase the power rating of those that show evidence of overheating in the past? (This is what I suspect has already been done to a couple of them.)
Thanks.
