Hi everyone,
I'm trying to repair a Pioneer DJM 600 mixer, which has a really bad and "off" sound... I've desoldered all the rotary potentiometers (they're Alps, I believe...) and cleaned them by completely disassembling them, but they're really worn out, and the result is not conclusive.
Before cleaning, they were giving off really loud crackling noises... after cleaning, no more crackling, but the sound is scratchy on the high frequencies...
So I'd like to replace all the potentiometers, but the cost of original replacements is really too high...
Can anyone help me identify a compatible replacement?I'd need both the ones that control the HI - MID - LOW frequencies (Pioneer Code dcs1054 djm600 gain DCS-1054]And the one that controls the gain (Pioneer code: DCS1053)
Could they be B10K B103 from (10kΩ-B)? but of what type? 12 are needed that lock in the center (hi - mid - low) ... 4 are needed that are linear ...
Can anyone help me please?
PS: is it necessary that I attach the sound coming out of the speakers?
PS2: I attach photos of the official spare parts... one potentiometer costs from 10 to 25 eur
thank you in advance

Is the poor sound the same on all outputs (xlr, rca, headphone)?
Master fader been verified as ok? Those get a lot of action over the years.

I've changed all faders with new one, so I don't think they are the problem
all channels are poor in CD mode and Line mode (I haven't verified the phono channels)

Thank you for the suggestion... but there are 2 kind of pot:
- Gain Pot are "linear" without central block
- hi - med - low pot have a block in central position
the 2 links are these different type?
If you do this, you should use a mainline distributor selling brand name, high quality parts, not fake junk from AliExpress.
What is your time worth? What is a lost event worth?

Yes, but it looks like the only difference is the shaft length (25mm vs 28mm). Not sure if they have a center detent or not, since it's not mentioned in the seller's description.
Basically, you need the Alps RK14K. You should check the datasheet to be sure which exact type you need.
They’re also available on Mouser and DK, so you might want to look there to make sure you get the genuine ones.
