Hi all
This is my next project .
Rebuilding PSU & require values of R36 & R47
Both measuring around 650R .

Re: Soudcraft Spirit M12 mixer schematic please
Found this site
Looks like they have been replaced using 680R types

Re: Soudcraft Spirit M12 mixer schematic please
R17 also cooked . Connected to pin 6 of IC6 ( UC3842AN ) , which is faulty as well .
Can anyone help with the value ?
I'm guessing 22R or 220R ( see picture )Attached FilesComment

Re: Soudcraft Spirit M12 mixer schematic please
Pulled datasheet for the UC3842AN & pin 6 is the gate drive output to FET .
Diagram shows resistor as 22R ( see link )

Re: Soudcraft Spirit M12 mixer schematic please
Last , but by no means least FET 1 ( P7NB60FP ) , S/C . Manufactured by ST Electronics .
With PSU in stand alone , gradually increased AC supply using the variac .
No big bangs which is good & all secondary supplies seem to be present .
Will fit PSU back into mixer next week , when i have some free bench space to test fully .Attached FilesComment

Also , before i forget , the two 47MF ,50V electrolytic caps on primary side of chopper required replacement due to poor ESR .Comment

D2 looks cracked, broken and possibly part of the snubber networkComment

Hi redwire , yes it does in the picture but it's absolutely fine .Comment

Re: Soudcraft Spirit M12 mixer schematic please
Thanks Khron , will check it out , although seems to be all sorted .
Just need to fit PSU back into mixer & test .Comment

Hello dear audio friends.
I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
Thanks in advance if anyone can help me with this schematic.
Of course, all information about this digital mixer and possibly references...07-24-2023, 06:40 AM -
Hi - I am looking to replace faders on a mixing desk from the early 1980s. They are tired and worn. I'm new at looking at schematics and would really appreciate your help and expertise on replacements.
The current faders are 88mm long with 60mm fader movement and are 10K B (which I think is a linear fader). They have been swapped out at some point (tell tale signs of additional screw holes a few mms below the top screw hole).
I think the schematic suggests 5K B faders (but as a newbie I'm not sure if I am even looking at the correct part of the schematic!?). I have... -
Hi guys
Does anyone have a schematic for this? The fault is both protect lights on. I fixed one problem already that was causing the negative rail to both amplifier channels to go to -90V with +45V on the positive rail (It's a class G design)
I now have 45V on both rails +/- but one of the amplifier channels has about 20V DC on all the emitter resistors and it all reads weird because the base of the NPN output transistors is about 8V so they are reverse biased, yet the base of the PNP output transistors reads about 19.3V, so 0.7V less than the emitters so those appear be forward... -
Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic... -
Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this...
