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.
