30's Dogbone Resistor Physical Size/Wattage
#1

I am preparing to restore a 1935 Philco Model 610B and wanted to make sure I had all the potential parts. So I looked at the resistors and the schematic and it does not list the wattage. There is also not sufficient info to just use Ohm's Law for all of them. There are 3 sizes in this set, and I "think" they are 1/4W, 1/2W & 1W.
I thought I remembered seeing a file that showed these with a picture and dimensions for the lengths in the Library, but I can't locate it.
There are some links in a previous discussion to -

http://www.philcorepairbench.com/carbonres.htm
http://www.philcorepairbench.com/resistcompare.htm
These are all from Chuck Schwarks Philco website. A very valuable tool.

However, these links do not work, and I assume that the philcorepairbench no longer exists.

Does anyone know where I can find this, as it is good reference information.

Thanks in advance!

Thanks

Thanks Ron!
I do use this frequently, and not just for resistors!
But if the Part# is not known, I was looking for a graphic showing physical size/dimension and the corresponding wattage.
The Resistor section in the Library provides a lot of what I need.

Thanks!

Thanks
