Not to start a discussion about it, but a lot of times certain components are pushed because of their origin of manufacturing. This is purely political bias, and many countries (and their citizens) are guilty of this. The idea comes from supporting local manufacturing, patriotic bias....Thankyou for your thoughts chaps, i have read many posts people building mics and mentioning resistor brands, I guess they just being a bit OCD.
On the contrary, MO and MF are favourite as they are very tollerant to heat and loading plus very inexpensive. Take a look inside a modern valve amplifier for confirmation.I have wondered the same. Guitar amp guys swear by the carbon comps on power tube plate load. Don't think a preamp tube is going to push it into distortion though; not nearly as much power going through. I think it makes a negligible difference except for noise performance. I use metal films everywhere. It's not like they're worth their weight in gold. What almost certainly makes a difference is the use of film caps instead of electrolytic as used in older designs.
Actually, carbon comp resistors are more expensive because they are not made on the same industrial level than the other "modern" resistors.Some DIYers try to use NOS carbon composition but only because they believe that is their best option. There is no science behind it, just the thought that more expensive means better quality. Sadly, usually not the case.
Have you measured the two caps, and they both measured the same?Re capacitor sound ... when I was a kid I made a radio in a matchbox.the ZN414 chip , it worked really well sounded great with my hi quality earpiece, there was a .1 uf cap for output I was using a philips mustard I pulled out of old TV.When I tried other .1 uf caps so it would fit in the matchbox it just didnt have the warm bassey tone of the mustard.
No I was about 8 years old... all I was saying is when I built my littlre radio I reached for a .1 uf capacitor as per diagram I happend to find mustard, the raido sounded rich plenty of bass. But when I tried several other .1 capcitors in the radio none of them matched the sound of the mustard, just something I remembered from a long time ago.Have you measured the two caps, and they both measured the same?
