47-1230 Capacitors
#21

Thanks, I just have to find out if the .003 is uf or pf. Being new to tubes, im not sure which is the output tube, maybe I can figure it out by the schematic.
My set has like, 23 - 100pf caps, are you saying I should replace those with mica caps? Also, yes I was planning on replaceing all the resistors at the same time as the caps. Im sure to some its a dumb question but Can someone tell me the reason for useing mica caps instead of film caps? Is it because they are more reliable at those values? If so it would be a good idea to replace anything smaller than .001 uf with mica? Just trying to make a little sense in my mind so I understand how it all works a bit better. Thanks Chuck and Codefox for your answers, and anyone else that might add here.
