Does anyone know what the wattage rating is for these Philco resistor part numbers:

33-1171 (1 MEG)

33-1169 (500K)

Thanks,
Geoff

Juxging by the values you do not need more than 1/4W anywhere in a radio.
Those usually were 1/2W resistors they used for such values.

Thanks.  It is for my Philco 640 (schematic attached).  I have a scan of a Philco Radio Parts Catalog from 1936 and was able to find the wattage for all other resistors with the exception of those 2.

I dunno what the mfr specs are but you don't need anymore than I wrote.
The sole reason I use higher wattage is the resistors are longer and so can span more gap when soldered between remote points.

Thanks!!!
