Hi! <br>
<br>
I have experienced EXACTLY the same thing! <br>
<br>
The value of this pot is 1M Log. It's an ALPS-pot with splines.<br>
I didn't find any suppliers of this particular one where i live (Sweden)
so i orderd a similar pot without splines from
<a href="http://www.trimlog.se/" eudora="autourl">www.trimlog.se</a>
.<br>
Then I took both the new and old pots apart and put the original pot-shaft in the new pot. This required drilling out a small rivet (is that what it's called?) out of the end of the pot-shaft.<br>
It was a bit hard to get the shaft to attach to the new wiper so i had to drill a 1,8 mm hole in the shaft and use a self threading 2mm screw and a very small copper bushing to fixate it. <br>
But it worked perfect and my dr-55 is happy!<br>
<br>
Before you try this, ask your local ALPS-dealer if he can find the correct type.<br>
<br>
I'll put the schematic up at <a href="http://home.bip.net/daniel.araya/diverse/dr55-p4.jpg" eudora="autourl">http://home.bip.net/daniel.araya/diverse/dr55-p4.jpg</a><br>

Today I received my boss dr-55 drum machine. It was shipped to me, and was <br>
packed very well, but, after my first glance at it, I noticed something <br>
wrong. The tone pot was obviously bent, and I got curious and took it apart <br>
to see if there was any damage. <br>
<br>
Sure enough, the pressure that the tone pot received had broken the solder <br>
joints for the pot and pulled up the traces on the board, too. That's really <br>
not a big deal, the problem is, I removed the pot and I found that it had <br>
been broken when ever it was mishandled. I need to replace this pot for the <br>
tone control to work,and I'm concerned that I am not going to find something <br>
that fits in there properly. Does anyone have the schematics for this unit, <br>
or do you know the value of the tone pot and where could i get one? Do you <br>
think mouser would carry something that fits? <br>
<br>
As always, any information is very much appreciated. <br>
<br>
Thank you, <br>
