Circuit Overview:
      Along with the Eminent Solina STring Ensemble, this was one of the first string machines to hit the market. Read the SOS article about the birth of string synths.

Service Tips:
     Sadly the one we received was in pretty trashed condition. So I never tried to fix this one. But the notes on multiman will likely help some as well as solina. Bad divider chips probably common. These saj110's can be very touchy. They'll work sometimes in one application and not another. Fortunately they're socketed in these machines unlike Solina. Replace with SAJ210 or equiv.

Try our friend Lorenzo at Vintage synth parts for 6 euro each and qty. discounts

Semiconductorand misc. Parts:
Lots of discrete parts. I have some dividers SAJ210 for replacement of these. ALso I have a few sliders now that are used but good.
