I assembled this OPL2LPT replica using all linked parts from mouser and YM3812 from the linked aliexpress seller. I socketed all chips. Sometimes there is a very strong humming noise coming out of the speakers and other times FM music playback in games gets all desynced and broken. This is not a very good start... I used 1k resistors and a 100pf cap on the crystal circuitry. I test it on IBM Thinkpad T23 on Windows 98SE DOS mode
