PHILCO now furnishes a complete line of cartridge-type resistors suitable for replacement in any make or type or receiver, as well as for experimental and contruction work. These are of the highest standard material and workmanship, and all have the standard R.M.A. color code marking, for quick identification. The metalized type are available in the 1/2-Watt and 1-Watt sizes. Here is an off-site link to the R.M.A. Resistor Color Codes.
Here are some physical comparison pictures of older types, as compared to new carbon composition parts used today.
For further reading on this subject, see this article at PhilcoRadio.com website.
[Note: The charts below are a compilation of the available values and sizes from 1931-1935 inclusive.]
Quick Jump to: 1/4 Watt, 1/2 Watt, 1 Watt, 2 Watt and 3 Watt Sizes.
