Hello, I'm looking to do the bias mod on my DC-3, but I'm not clear on which 120k resistor should have the 470k piggybacked onto it. Is it the one in the bias supply or the one coming off pin 6 of of V6b (see schematic images below)? Can anyone clarify for me? Just want to make sure before digging into it. Thanks!

BTW, I'm pretty sure it's the bias supply resistor (first image), but wanna be careful...
