10k decoupling resistor

Looking at Dan's 67-68 layout on Mac's page, it notes that the 10k2W resistor across the preamp filter cap is optional; what exactly is that resistor doing and why is it optinal?

If its parallel to the filter cap, i would imagine its there to facilitate rapid draining of the caps when no loads (ie tubes) are present.

its not optional. the the two 10k's near the preamp cap is are needed.

Okay, I guess he was refering to the 10k that is in series with the 8.2k...my mistake.

Thanks guys.
