Okay, let's say I saw this board already somewhere... right, in my "old stuff" box in my office ;D It is linear power supply. It outputs +5V, -5V and 12V. Dont know about its current capabilities, but transformer is rated for ~60W. black ICs - discrete logic chips that gives button switch "EN" function and some basic control like short-circuit protection. Those hybrid goldy ICs - according to its part number - linear regulator with regulated output rated for 150mA If you want any more description about this board - you will have to wait till Monday, when I will be able to get to it |

Ceramic ICs look like 142ЕН1, 142ЕН2 VREGs. https://eandc.ru/pdf/mikroskhema/142en1_142en2.pdf |
