@Jeff
This is an amplifier board that i found in a chinese made (aren't they all?)
DVD receiver branded over here as "CAT 2002"
Just a PCB with 3 2020 Chips on, dit oes not look worse than my t-amp, even a little less cramped... and even the leads are documented
so, when I find the time, I'll try to fool around with it, after all it was just 29 Euros.
