[sdiy] schematic for juno-106 VCF/VCA

[rkmoore at memphis.edu]

Hello everyone,

A customer has brought a juno-106 to the shop where I work.  Three of 
his VCF/VCA IC's have gone bad and Roland no longer has replacements.  
Does anyone know of a source for these other than occasional 
appearances on ebay?  Also, does anyone have a schematic of what's 
inside this little epoxy-sealed inline IC?  I would hate to have to 
start telling customers to trash their 106's when a voice goes out.

thanks,
Richard
