The PHILCO Phorum

is there a good factory service information on the 38-116/125 i am having some troubles identifying some resistors. ether i have gone nuts are these 4 band resistors ? i know that other philco radios have good parts drawings

You can probably use the body-end-dot scheme on these. There was a doggone transition period where the BED was used before the bands became standard. So, if the body is orange, the end band black and middle band red you have a 3000 ohm resistor.

They aren't 4 banded but bed resistors. The the at the top of the first page the predominant color (body) is purple =7. End is black= 0. And middle band (dot) orange =3. Totaling 7 and 4 zeros 70,000 or 70K. The tricky ones are ones that the first two numbers are the same. If you look down 3 resistors below the 70K there's one that just has two colors. First time I saw one of those I didn't take it at face value but scratched my head thought what the heck?? But it's white white yellow= 99K. Nowdays it's replaced with a 100K.

so the one in the second photo should be 3k ohms

Looks like it. Body is orange, end looks black and center band looks red. That's 3K.

For the factory service info have a look in the Philco Library - Service Info section:

Here is a direct link to the service bulletin for 38-116 (Code 125):

Those are the IRC "BT" type insulated resistors. Philco used them heavily, but they turn up in other makes as well, along with early audio equipment. They are read the same as the dogbone type, except that a band is used instead of a dot (some early ones did use a dot). Many times, they are still OK.
