Philco 38-15 caps

When you have a project, it helps to post the link to the schematic as well.  In this case you can find one here.  When those can electrolytic caps seen on the top of the chassis failed, the repair was often done by clipping the old leads and then putting the new caps under the chassis or by replacing the can with another one but often of different values than the original because it wasn't critical what the value was.  If the cans are still present on the chassis you can cut them open and stuff new caps inside to retain the look of the radio.  A nice write up on recapping can be found on Phil Nelson's site.  I'd use 450v caps for those electrolytics since the schematic shows almost 300v at those points. (other folks please chime in if I'm wrong).  You also have a bakelite block capacitor which holds the two 0.01uF line capacitors that will need to be changed out.  Morzh has a great thread on how to do the change out.  Data on how they are wired up can be found here. Those should be safety caps.  Some info on safety caps can be found here.  

(Mike...cap #30 is a 2uF + 4uF. )

Thanks Bob. I never heard of a bakelite block capacitor before, but was wondering what that was. I looked at Morzh's thread on how to change out the caps. Very well done. I will have to do that myself.
