Resistors for Predicta

[Tony F]

Hello All, I normally do radios, and not tv's. So I'm going to start on pulling this 10L43 mainboard and replace everything (well caps, resistors, and couplates) Anyway, are carbon comp resistors preferred over metal film? (if so,..why) or is it ok to use metal film throughout this set ? Does it have anything to do with frequency stability, drift ? Other factors, than just replacing all the caps and maybe just out of spec resistors. I really want to do this right. Being in Canada, we just have to jump through more hoops than you guys in the U.S. and we end up paying more than twice for everything ( parts, shipping and duty hassles). I normally deal with Dave at JustRadios, but he doesn't have all the different resistor values and the one supply place in town leaves a lot to be desired.
Thanks !
Tony
