Rare SIEL OPERA 6, a cool Six voices polysynthesizer, warm filter section, 3x LFOs!! Using SSM chips, basically a very good sounding machine!
It mount 2x SSM2031 VCO, 6x SSM2024 VCA, 6x SSM2056 ADSR, 6x SSM2044 VCF !
It come in very good shape, panel is clean apart some very small signs of the age as you can see on the auction photos, only the right side end bottom cheek is a bit broken but generally in GREAT cosmetic conditions.
Working conditions: when it power on the panel appears blocked without any sound, It need to be serviced, it has all its components inside, only the internal battery was replaced with a new one, there is NO battery acid inside. My tech told me that for sure the problems is caused by an IC called TMS7000NL-2 in the CPU section (I’ve just seen about $6 on ebay). I twill be sold in AS-IS conditions since it deserve some tech attentions.
