Care to elaborate for my own edification? My understanding is that carbon comp resistors drift over time. Would that not be an issue for germanium transistors?
Whoops said:I don't think so, it's more of an era thing, and some people like to match to type of components used at that time, like having germanium transistors with carbon comp resistors, or having carbon comp resistors in vintage style Fender amps.
Personally I always use 1% Metal film resistors and I couldn't care less about carbon comp resistors. Yes it's true the value can drift over time, also drifts with temperature (the germanium transistors drift much more) , they are also more prone to humidity and have more noise, I think if the manufacturers at the time had Metal Film resistors they would have used that.
Saying this if I had an old/vintage mic pre like yourself I don't think if I would change the original resistors if there was nothing wrong with them, I would definitely change all the electrolytic capacitors without even turning it on.
just my personal opinion, other people will have different points of view, hope it helps
