Philco 38-12 question
#12

The resistor seems original. I probably would leave it be, considering that it is within tolerance for 270 Ohm and not that far out of tolerance for 250.

2M resistor is fine.
40K is also fine.

If you want to replace them, do it, but it will work fine as is.

PS. Did not see the original photos of teh whole chassis; the middle tube, the 75, the 2nd Det/1st Audio, is supposed to have a shield around it. If you decide to align without it, you might get squealing.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
