my friend got a soundcraft 200b for free and I want to refurbish it a bit.
After cleaning everything I want to do the Eddie Ciletti grounding modification.
Then I would recap everything seen to this post of Jeff Deff:

For the input channels with the variable midrange:
Replacing the (2) 47uF/63v phantom blocking caps (C1, C2) with 2 100uF/63v Nichicon PW series.
Replacing the (2) 100uF/10v caps before the input gain pot (C3, C4) with 100uF/10v Nichicon PW series. Do not replace these with 1000uF caps as I previously stated or you will get oscillations at high gain settings.
Two 100uF/10v caps are parallel (C9, C10) and attached to one leg of the trim pot. Substitute these with one 1000uF/10v Nichicon PW series.
There are (3) 47uF/25v coupling caps (C15, C25, C29) which I will replace with 220uF/35v Nichicon PW series.
The power rails have (4) decoupling caps (C16, C17, C30, C31), 47uF/25v which I will replace with 470uF/25v Panasonic FM series.
There are fusing resistors (R22, R23, R61, R62) before these decoupling caps that I will replace with 10 ohm, 1/2 watt 1% metal film resistors.
There are (2) 2u2/50v caps (C26, C27) that couple the transitors that drive the LEDs for the peak and on indicators. In the circuit these are electrolytics, is it worth putting film caps in here?
In the master section, tape returns and aux sends there are an assortment of similar caps that I will also substitute following the same guidelines.
The problem is that I have the fixed midrange EQ and not the sweepable where his recapping post is based on. Some of the capacitors are matching and some not (for example: my capacitors only count up till C24)
So I'm a little confused which caps I should replace and which not. Does anyone has done this mod to the fixed midrange channel strips? Can't seem to find a post on GS that summarized all of that.
Appreciate your help!
