Re: VFD help

Hey there,
There must be really good quality sockets in these Oberheims. It's 
the only electronic thing I have ever seen with a socket for every 
chip!! I have found chips just rattling around in other gizmos but 
never in my OB. I have an anvil case for mine and I have had problems 
were the keydeck moves a bit if it is stored on it's side during 
transport. I have a MATRIX 1000 that has just been through hell.
Except for a scratchy pot its works fine.

I agree the modern stuff seems very flimsy and buggy anymore. My emu 
XL7 has all kinds of soft bugs that will never be fixed by the 
manufacturer. I notice the european stuff (Nord or Virus) is very 
tough. A few weeks ago a friend sent me a MATRIX6 rack that he 
thought was fried. I opened it up and the ribbon cable had just 
fallen out. Yea
