Hi apERNA1985 -
Here's a clearer version of the schematic (converted from DJVU). KCMike - not sure why the one you converted (from the same source) came out low res.

The 117Z3 tube in your set is labeled as the rectifier - it's converting AC to DC. Electrolytic caps are typically rated for volts DC. Have a look at the schematic and replace with at least the voltage listed for the original part ratings. The voltage rating should be marked on filter cap (it's a combination can) - each section may have a different voltage rating. If you want to be on the safe side just replace with electrolytic capacitors rated at 450VDC (or higher). Capacitors of sufficient voltage rating may not be available locally - you may need to mail order them from someplace like radiodaze.com or justradios.com.
By the way - I'd suggest checking out Ray Bintliff's excellent introductory books on radio repair.

Tons of great information in both volumes.
