crumar multiman

[sam]

I am fixing and restoring my multiman...I am trying to work out why the envelope section doesn't work.

The pots are fine...

I can't find any schems...

So any info would be great from anyone who has worked on one here...?

SUPER...Thank you..I find it's the trigger to the envelope is not working...

[sam]

I noticed these are for the later S version..Mine is the mk 1..

Is there much technical difference..?

[sam]

The problem was in the keyboard, I had to strip down and clean / calibrate the keyboard contacts.

The next thing is some of the key contact springs a getting old and less taught.

Are there any tricks to fix these..I have no replacements.

[sam]

I found a solution for the springs...Must post photos to explain..

Next fault....On the bass section/piano...One note is out of pitch..

Checked the dividers OK
Voice board is OK

Any ideas...?

[sam]

It's solved...A wire going to the dividers was broken, it took some time but it's fine.

Just need to replace some caps and clean up the boards ....

I got this in a bad state but hearing it now it's all worth while.
