16 Inputs - Ready!

I have reworked all 16 IO modules. It has taken about a month and a half. about 1.5 hours each day.

Tangent 3216. circa 1979 Recording Console that I am rebuilding.
All modules have been reworked and I am testing audio through the system.
There are a few problems remaining in the metering; a VU and LED meter problem.
Ready to start the patchbay!

I powered it all up and it sounds great!. I tested all the mic pre's and tape inputs and outs.
Then I did tests of the submaster busses. I have one VU meter acting up on #10, I will torubleshoot it.
A 4016B Comparator a TL084 opamp and 3- LM336's for the LED drivers. the Peak Reference transistor pair is fine... and another VU modeul works perfectly when swapped out...


The Master Module is ready.

I put in the TB Oscillator module and it is working to all busses except 16. I think it is the finger module.

TB Osc Module - Peak Ref adjust (+15V)

TB Osc Module - Main board - ICL8038 VCO . I have a mod idea!

I read the datasheet on the ICL8038 VCO IC. The Tangent 3216 provides a sine wave output to the MIX, CUE, or BUSS. I read that the IC also supports Triangle and Square waves on pins 3 and 9 respectively. I think I will pull those out to the patchbay for a handy tone reference jack! Just add a resistor to ground. I will try 1K, 10K and 100K. Cool...

I also had time this week to build some shelves that I promised Susan long ago... came out pretty good! lots more room for storage now... ~30$ of wood and 3 hours...
