Hi guys,

I've had a GSSL change in sound over the years, as things do. Less brilliance on the top-end....
I'd suspect ears instead...

Running turbo mod, side chain mod, THAT 2180B vca's. Should I start with the electrolytics?...
... would address the opposite side of the audible spectrum, lacking low end when electrolytics loose capacitance so the hpf rises.

Hello everyone, it is my first post :), although I have been looking for information in this forum

First I thank the audiokitchen chef who is a very nice guy and he supplies me the pcb very fast ;)

I have several questions about the construction of this compressor and if someone were so kind to help me

1º Question
I am going to mount that 2181A, the question is, what resistance do I have to mount in the% in the photo that I am going to put? In the main vca I have it more or less clear but in the sidechain vca I don't

(that 2181a data)

(web where there are various data)

2º Question
I can't find the 22uf low ESR electrolytic capacitors of 25v and I have seen these 50v ones that seem to be 5mm in diameter the same as the 25v ones, I suppose they will wipe me out?

3ºQuestion
Do the resistors come to change the sound a lot? Since I plan to buy from the yageo brand

4ºQuestion
to make the connectors of the main PCB and the auxiliary pcb, would it be worth awg22 cable? in xlr if I am going to put mogami cable that I have here

I leave you here a list of components in case someone is worth a reference, although I do not know if it is completely fine

Thank you and sorry for my English from Google translator. My native language is Spanish.

hi :)

The 1st question is solved, the resistance in the sidechain vca marked with% is a 47ohm resistance because I am going to use 2181. if I were to use 2180 I would not put any since pin 4 of the 2180 is removed from what I understand

The 2nd question is also solved. You should not have problems to put 50v instead of 25 because they are the same size. I only have the doubt if the brand resistance yageo are good but for now they are the ones that I am going to mount since they are the ones that I have

thank ;)
