Especially if this observation is as extreme as you say you should consider it is quite possible there could be a build issue. Visually recheck and verify all values by color band and part number. For example R11 is 470 ohm sometimes mistaken for 470k ohm. Since I have not previously heard anyone suggest an issue like this and it was not my experience this makes it worth a serious re-check.
If we have pictures we can take a look as well.
