Replacement Faders/ Tone Arms

[a burdenless pig]

Hello!
I have had my djm 700 mixer and technics 1200 turntables for quite a while now and am noticing some problems. Both were bought at a very cheap price used. I am therefore looking for 4 replacement faders and 1 replacement crossfader for the djm and 2 replacement tonearms. As I want this to be a learning experience I want to replace all the parts myself and so i have some questions. I have seen some people saying that there is a difference between the 1 and 4 channel faders and the 2 and 3 channel faders on the djm 700. If so could someone explain these to me? I also would love some advice for the best place to go to get good quality fader and tone arm replacements at a cheap price. Also as an aside I would like to know how much soldering is required for both replacements? I hail from Canada but I am able to drive to the states if need be to pick up my order.
Thanks for the info!

If you buy the fader without the PCB and solder it yourself, there's no difference between the channels. 1 and 3 have a different PCB to 2 and 4.

Also how much soldering is actually required? TBH i've soldered something like once in my life haha

That looks right. The pins on each end of the fader need to be desoldered for the old fader, then soldered for the new one. There should be plenty of tutorials up on Youtube.

also just wondering if its worth buying an innofader crossfader. My crossfader now bleeds like mad.
