MV-8800 complete disassembly with pics

15 Jul 2016, 11:28

What´s up fam,

I had to change some sliders on my 2nd MV so I needed to disassemble it completely. I am sharing the pics I have taken during the process, I hope they come in handy for ya...

I haven´t documented the few minor steps like removing the backplate, the sidepanels, etc. I think you guys can figure this out yourselves easily ;)

I don't know how I missed this post. Danke Soul One!
I really need to break both my MV's all way down to spring clean them.

BTW... What was the part number for the sliders and where did you get them from?
Thx!

I got the sliders from Roland Germany directly. Can´t remember the part number, but you can easily look it up in the service manual.

I wasn´t able to source this part from Mouser or the likes because it was discontinued a long time ago. Luckily Roland still had some.

The original sliders were made by Panasonic. What makes them special is the pin layout. Like I said, I wasn't able to source them for a price that's cheaper than the ones from Roland directly. I saw them on alibaba and some other sites...in some cases for ridiculous prices!

Unfortunately only from the part where the sliders are. Let me know if that would help and I´ll upload it here!

MV-8000 Slider Repair...

Alternate Slider 30mm (10 k ohm) replacement - Panasonic EWANA0C10B14 - that fits the through-hole pattern on the Roland MV-8000 PCB (you'll need to un-solder/re-solder replacement), but also must solder a jumper wire (see image below) between two pads on PCB (on underside) for each slider replaced. I am assuming this slider replacement will work for MV-8800.

Here is link for Reverb.com to purchase this Slider part:
