EII guide bushings

[AlphaC]

Hi

I'm fixing up a EII+ and I was wondering if anyone have a source for the keybed guide bushings?

Cheers,

I believe the Oberheim Matrix 6 used the same key bushings you might have a better luck finding those.

Hi AlphaC,
I'm working on doing a conversion of a single bank EII to a dual bank EII+.
Could you post some detailed pictures of your digital board.
I'm trying to reverse engineer the change of going from a single to a dual bank memory using the Rev1 digital board.
Thanks,
Dana

Hi Dana

Thanks for the OM6 tip, I will look into that.

I guess you will be needing pictures of both sides of the board?

Yes that would be helpful but I think it has to do with different chip placed where there is a missing chip in my board for comparison.
I don't think that they would have made the effort to create a new board then have to turn around and kludge it to get it to work.
So I'm guessing that I have a chip that is different or one of my empty slots has a different chip in it.
This information has definitely been lost in tribal knowledge at Emu Systems.
Thanks,
Dana

Thanks for the pics

Yeah that is definitely a plus model configuration.
I noticed that your drams are the 150ns variety.
I'm guessing the fact that the piggyback mounts where never soldered in that this is a high 1200 serial or even 1300 series serial number.
Did you take of the midi jacks and foot switch jacks?

Yes I removed them because of the level of corrosion on them. This synth seems to have been a victim of a basement flood or something similar. There was mud and dirt on the inside and alot of rust everywhere so I'm doing a full restoration. I'm in the process of replacing a lot of corroded ic sockets.

Hey AlphaC,
Any chance I can get some photos of the  underside of the digital board?
By the way how is your restore going?
Thanks,
Dana

Hey AlphaC nevermind I was able to get the upgrade to an EII + solved.
Thanks for the pictures that you provided before very helpful.
Thanks,
Dana

Hi dfiorucci

Sorry for the late reply. Congrats on your successful conversion =)
Now we need to copy the two HD boards so we can have the DREM.

My restore is ongoing here: http://forum.vintagesynth.com/viewtopic.php?f=1&t=105483&sid=003120828f9e9898827faf0c899681d9
