I was able to grab this massive Realistic STA-2000D in a gear lot with other stuff.
Unit turns On but there's No sound.
I feel an instant "click" when it turns On (there's no delay like the usual protection relay clicking out - this one clicks right away and the "click" is hardly perceptible).
Unit is currently connected to a Dim-bulb (75W) Tester, the DBT goes into a variac (set to 117VAC). DBT lights up very bright and then goes faint as expected.
Upon initial visual check, nothing seems to be burnt.
Connected Pre/Main jumpers, same results.
Connected directly into wall outlet, same results.
Tried all inputs (Aux1, Aux2, Phono, AM, FM and Main In, same results. While changing stations in FM, the FM tuning meter seems to change (like it is picking up stations).
Tried all outputs (Channel A, Channel B, Pre Out and Headphones), same results. Power meters never moved.
All fuses tested Ok outside.
Removed all four Output transistors, same results: just an instant but hardly perceptible "click", not the usual relay click. Installed Output transistors back.
Service Manual can be found here.
Schematic diagram can be found here.

Any guidance will be much appreciated, PLEASE
