Mac 128k analog board recap, old C6 soldered with resistor

[captjon320]

Hello all,

I'm recapping three Mac 128k analog boards. I took the easy path and ordered the cap kits from Console 5. I am on the 2nd board and noticed that the old C6 (22uF 50V) cap has a resistor attached to it. The other two boards did not have the resistor attached and the old capacitor values are the same on all three. The replacement cap is a 22uF 63V, which I assume is due to newer vs older part availability.

I am leaning toward not putting the resistor on the new cap, but wanted to ask the community for input as well.

What was the resistor connected to? It seems to be pulling down that part of the circuit for whatever reason. Are the boards the same revision? I can't imagine it was placed there randomly.

Edit: Oh, look at the boards closely directly next to C6. The very first early 128k boards have that resistor, but later boards added a spot on the circuit board for a proper placement.
