Mdk Mb-17 W Schematic Online

Given the age of the MB-17 W (likely 1985-1995), some engineers are now replacing the entire board with modern equivalents. Using the schematic, you can map I/O functions to a microcontroller like an STM32 or an Arduino Mega.

For example:

However, for restoration projects—especially in vintage audio or test gear—keeping the original MDK MB-17 W operational is preferred. The schematic is the key to that preservation. Mdk Mb-17 W Schematic

While the exact PCB layout may vary by batch, the MB-17 generally follows the simplified 4-transistor JLH Class A circuit per channel. Given the age of the MB-17 W (likely

Later revisions of the MB-17 W include microcontroller or glue logic: While the exact PCB layout may vary by
