Stk3082

I found some NOS modules in my parts bin. Can I make anything usable out of the module? If my memory is correct they were used in integrated amplifiers in the 80's. Anyone remember?
What would it take to make an amplifier out of one of these?

a datasheet perhaps

well this should be a driver stk ic mostly used as a driver for a couple of transitors for sansui amplifiers .....

nice circuit ...produces a lot of power but SOA of the all device is way overestimated resulting this b1000 amps to fail quiet easy .....

i have a broken one ,,,,,, never bother to fix it ....if i ever do i will replace trafo to something lower for more safety ....

A stereo driver IC rated at 4W (max) ±57V (max). Single ended diff input, Vas, and CCS.

Intended to drive high-gain double EF output modules with bias circuits (STK 0050) and triple EF (STK 1050).
