Suppose you were going to go through not only the power supply, but the amp driver boards in a 30 year old receiver or amp. You already have decided to replace the electrolytics and some other parts, check solder joints, etc. You want the thing to work reliably and sound its best for many more years, and so have decided to replace the resistors. All of them! Now, what type would you use? I have read many opinions, and some differ as to the type of circuit (i.e. amplifier versus R.F.). Anyone who has done this care to offer guidance? I should add that I am looking for that sweet spot of cost/performance, the most bang for the buck. Obviously, the largest cost of this is your own time. Many thanks for your thoughts!
A subject highly debated, and full of mis information from way to many who cling on to old crumbly carbon resistors as the standard, and think you have to cling to carbon resistors for that vintage sound.

Here's a great statement:
"Standard policy is to use Metal-film resistors, and my preferred type is Vishay-Dale
CMF55 or CMF60 for 1/4W and 1/2W applications.
For higher wattage applications, I use Vishay-BC PR
01, PR02, and PR03 Metal-film types."
I have stuck to that for a long time and use ONLY the aforementioned in every vintage repair or restoration or anything else
with 100% satisfaction.
Ive got a audiophile ear and temperament and completely staying away from carbon, especially modern Chinese carbon
(used to be Japanese or Taiwan) is something that works.
If youre going to consider or debate cost, you can thank the Chinese for cornering the precious electronic metals and substances
market two decades ago. Vishay metal film cost what they cost.
