I am looking at the sams right now and in the parts list the capaitors to change are listed with voltages of 200 volts , 400 volts , and 600 volts , those are the paper wax , the others not marked or shown as 500 volts and 1000 volts are micas or ceramic , you can usualy tell by the value listed , the paper/wax have values like .01 , .22 . .002 . etc etc , the micas are listed like 82 , 1500 , 270 , etc etc , there are two 1000 volt caps that are not mica or ceramic and are paper caps , C94 is .039 at 1000 volts and C95 is .018 at 1000 volts , if you can't find those exact values something close will do like .015 or .02 for .018 , .04 for .039 or .035 .... this might help - if you copy the page that shows where each capacitior is you can write on it the value and voltage so when you go to put it in the set you have a guide to do them one at a time and check off on that paper the ones replaced ...... as far as resistors you might want to check the big long one mounted to the back , it has 3 sections , if you are not getting proper readings check back here because they can be tricky to read sometimes ... if you want to be sure you could go over ever resistor in the set to see if it is the right value , some may read wrong and will have to have one end disconnected to be sure it is the right value , or just check the big power one on the back which i already mentioned but if you do that without reading the others if there is a problem one little 1/2 watt resistor thats no good or way off in value could cause a problem , however some just replace all the capacitors / electrolytics along with tubes and then bring the set up on a variac slowly up to about 105 volts to see what goes on , or just turn it on..... any problems comeback here and it will be discussed.

Thanks!

I'm used to working on old regen radios that may have, at the most, 20 caps. I should have recognized the difference between the "low" and "high" values. Feel kind of silly now . . .
