Much respect to @analogoutput , he is a pillar of this community for sure.

So far nothing except the knobs are a bit weird and they were supplied separate and non of them seem to fit. But I have a bag of Moog like knobs that seem to do the trick. I got it powered up after building a +/-12v modular power supply and cable set.
Just building a MIDI to CV converter for it.

So its VCOs were all dead, faulty TL074 chips and a bad power connector to VCO 1, the rest just had TL chips. Went through and calibrated everything ok.

Picked these up today for $1 for the lot.
Apparently they were made and used by a broadcast engineer as test tools. So far two of the 3 LCD displays are working and pretty sure the third is too, just need to connect a 12v supply, but I have none with the correct barrel plug.
One will be mates with a raspberry pi zero in the near future. Tracker or orca running retro style 
The surprise is the two audio level meters, they have some very nice but dated DSP cards with dual two channel codecs w/ 24-bit DACs. The are adsp-2184 microprocessors with references to windows 3.1 in the datasheet. Struggling to find any information on these board and there is no hint what power supply they might want or what the dip switches might do beyond âdisplay modeâ They are not the official ezkit dev boards. Any hints or ideas on where to look or ask appreciated.
And the other few boxes:
Mains voltage amp meter in homemade aluminium box.
Amp and speaker with 12v worth of AA batteries.
A/V test bar generator (this was a surprise as it wasnât mentioned in the auction, and super handy to test the displays + bonus bnc to rca converter)
