   I am recapping a Philco model 3650.. I got the paperwork concerning the Bakelite blocks from
''the Philco Repair bench.. [Chuck]
 I have a block with the numbers 6287DU in the radio.. My paperwork from Chuck  only lists  block with these numbers..6287CU,,6287ODG,,6287ODU,,6287SG and 6287SU.
     All of the blocks listed tell me to use a .15uF
    I am concerned with the part  80 in the schematics and it shows the cap to be  shows a .03 uF  in a bakelite block.  I don't know which value to use.
   These blocks are a real pain to figure out so I hope someone can help me out.
   Thanks  Dan in calgary

Hi Dan,
   The 6287DU is a dual capacitor unit. Both values are.015 uf. Looking down on the block with the mounting hole oriented on your left, you will have three strips (terminals) . From left to right call them 1,2, & 3. Wire one cap to strip s 1and 2 the second would be wired to 1 and 3.. If you do not want to melt out the tar and  remove the capacitors you can use a drill bit barely larger than the rivet hole in the center of the strips to drill the opening a little larger which will sever the wire connection to the capacitors inside and then just solder the capacitors to the strips ( terminals) .
   The blocks are easy to figure out once you understand that they should all be numbered. Knowing the number you can determine the value using the Philco or other data. There are a couple of publications that explain the blocks well and remove all the mystery.
                                    Good luck .
