I want to gain output level for an Quad 34 preamplifier. Seems to be pretty straightforward with this attached guide.
Simply change R118 and 121 for a short and put 3,3Kohs in R119 and 122. This done to be able to have the right inputlevel for a old Quad 2 who likes 1,6volts . I also have a bunch of 33s and others that reqire 0,5V.
I have seen others set a potentiometer in the back of the 34 to be able to change output settings. Anyone now how to do this mod?

Just do what it says in the service manual you quoted. Not much point in a pot when you know exactly the level you need. Never seen that, and I've serviced heaps of them.
33s do not 'require' but output 500mV. Do you mean 303s?

Ok thanks for advice I probably change the resistors then. You are right I meant 303s. I have several of them. But it was for easily changing between an 303 and a Quad 2 and keep 34 as preamp.
