41-285 capacitor help needed!!
#1

Hello everyone!
I am new to this forum! I have re-capped several radios in my collection, including a 37-610. My electronics knowledge is very basic, and I posses no test instruments outside of a multi-meter. I received a Philco 41-285 as a gift this Christmas! It is in beautiful condition and performs very well. I ordered the schematic and technical info from Ron's Philco web site, and am now ready to begin a re-cap of all the electrolytic and film capacitors. My problem is that the capacitors in the radio and those shown in the manual do not match. The radio has had the AC transformer replaced and several of the capacitors a long time ago. The repair was very well done. Here is a list of the capacitors in question:

Capacitors in radio now-------------------Capacitors shown on schematic

49. .002 mfd @ 1000 V-------------------49. .003 mfd @ 1000 V
45. .002 mfd @ 1000 V-------------------45. .001 mfd @ 400 V
33. .002 mfd @ 1000 V-------------------33. .05 mfd @ 200 V
55. Not in radio at all---------------------55. .01 mfd @ 400 V
57. Not in radio at all---------------------57. .002 mfd @ 400V
62. 16 mfd electrolytic--------------------62. 12 mfd electrolytic

All other caps in the radio are original, and match the schematic. My question is should I re-cap according to what is actually in the radio, or change it to match the values shown on the schematic? Any help or advice will be greatly appreciated!

Thanks to all in advance!
