2 vintage ETI Series 5000 One Third Octave Graphic Equaliser modules
For use in a stereo system. Pair (one for each channel) graphic equalisers, circa 1981. Part of an original DIY ETI system, rack-mounted for 40 years, now decommissioned. Were working at the time the rack was dismantled. Note: sold as is - not tested by me. Good cosmetic condition, very clean internals. The upper unit has an IEC mains AC connection; the lower has it's operating volatge passed down via a 3-pin din connector.
