What is this?
ELS122:
What is this thing?
bob91343:
My wild guess is that it's something out of an electronic musical instrument. Have you tried energizing it?
ArthurDent:
This might be a linear power supply with multiple outputs. The large heatsink has a metal bracket with a large round hole that could have been for mounting a fan for the output with the highest current, fused for 6A. There are three black heatsinks, two of which that are probably for a +/- supply, each rail fused for 1A. The last heatsink is for a forth output that is fused for 0.5A. There were probably 3 LEDs near the switch with the black "~" cap and one has broken off. The 3 LEDs were probably indicators for 3 of the outputs. This supply was probably removed from some piece of equipment that died and was used as a makeshift bench supply.
tkamiya:
Looks like there are two very old fashioned IC on the board. What does it say? Looking that up should tell you what it is.
I think it's a linear power supply like ArthurDent says.
DannyTheGhost:
This board uses transformer that is specifically used for different vacuum tubes (multiple outputs of 6.3V).
My best guess would be power supply board for anything from Soviet test equipment with CRT screen (starting from oscillocsope).
