Nope :-) I am looking at the spreadsheet now: R17, R18 are 392, but with the comment: initial value, could be optimized for expected power/load conditions for R17.

on the schematic i got for A30, it is only R18 that is marked 392ohm. but i see R17 is marked 392ohm on the spreadsheet for A30. however. it is marked 221ohm on the A60 schematic.
so if it is A60 you are building. stick with 221ohm.

Thanks, I will go with 221 first and then will see!

There is only one thing between me and assembled A60 bock — wires. Bought 12awg teflon wires, but the strands are covered with some "silver" metal that does not soldering well :-(.

another reason to stick with good old trusty copper
i just take a extention cord wire with 3x1.5mm2 and strip it
but for the A60 you can go for something a little more beefy.

Guys, what to do with R19(R13 pcb). It's 5622?! I have a multiturn trimmer for 10k, or find something else?

I have 12awg, 14awg and kimber 19awg wires. Which are better suit for +s, +g? I am thinking of 12awg for +c, +v and smaller diameter for other two.

I think its 56,2k

Seen this kind of number in x2 manual.
means 562 and 2x 00 is 56200ohm
Last digit says how much 0 you must add

could also be that i`m wrong

look there

Pass Labs X2 REV1 Relays?

I think Pass forget to translate R19 and R21.

When I will do my Aleph60 I will try R21 1,5k and R19 56,2k
I`ve looked at the serive manual from the Aleph30 there R19 is 47,5k
why should it be so much different in the 60?

I will try when time is come hopefully my Amp dosn`t burn down

greets Alex

5622 means 562 x 10^2 = 562 x 100 = 56K2
