That very interesting. Mine's a B190000+ so that explains why I have the 1.8k. I still like the shorter characters and will likely either replace it with a 953-ohm or leave the 2k parallel resistor.
Thanks so much for that tidbit of info.

details regarding MOD3089 for a 7704A
There was a mod on Beaverton built 7704A's which changed R3468 from
953ohm to 1.8kom. This is opposite to the Guernsey change. So either the
Guernsey mod sheet is wrong or for some reason they changed it back what
is was initially.
This is what Mod Summary says about Beaverton Mod M24523 done at B180000:
"To allow usage of the Readout circuit board in another instrument R3468
953ohm, (pn 321-0191-00), was replaced with a 1.8kohm, 1%,0.125W metal
film resistor (pn 321-0641-00)."
