Philco 38-12 question
#11

I have finished identifying and testing the caps and resistors on this 38-12, except for the final resistor on my list. On the schematic it is identified as Item 25, a 250 ohm, 1/2 watt. However the color code appears to indicate 270 ohm, 20%.The colors are red, pink (violet), brown and silver. Photo attached.
I lifted one leg and it measures 306 ohm.
What should I use to replace it?
Only two other resistors were out of tolerance:
Item 9, a 2 Megohm (no wattage speced) tests 2.36 Meg, and Item 11, a 40 Kohm measured 49.5.
Thanks for your patience and assistance.
So glad to get started on this job, and I have several more radios I plan to work on.
