Ronnjay, here is a Kit 1 schematic which I believe corresponds pretty closely if not exactly to the configuration supplied to Rebbi. (See page 3 of the pdf for a clear presentation of the schematic, although you will have to refer to the first two pages for the reference designations of the components). As you will see, C1 through C4 provide noise filtering and decoupling for the B+ that is supplied to the small signal stages.
Consistent with Rebbi's explanation of the reason for the two holes and pads at one end of the capacitors, it appears that some versions of the kit were provided with physically large 0.015 uf capacitors (see Section 7 of the manual), and others (including Rebbi's) with smaller capacitors which are 4700 pf according to the schematic. Both values seem to me to be within reason, with the choice depending on the range of frequencies that are considered to be most likely in need of being filtered.
Rebbi & Mapman, thanks for the nice comments.
Best regards,
