Famicom Disk system RAM adapter volume is too low!
« on: July 30, 2016, 06:44 PM »
i have the ram adapter hvc fmr 03, on original famicom i have low volume on bios and floppy games....years ago worked fine. the famicom have no problem in sound with normal cart game and with edn8 with exp audio games too.

i checked the connections on U5 and they are ok. can be this component? the floppy games are still working fine but the sound  is low.

i changed 1x 47uf    2x 1uf     2x 0,1uf 25v nothing changed...help

Yes, although the "amplifier" is really just a hex inverter.
