According to Beoworlds page about Beomaster 6500, it has the RIAA build in. But according to Beocentrals page regarding the Beogram 6500, it has the RIAA build in, not the Beomaster 6500. So which one is right?

BG 6500 has a RIAA build in as standard.
However BM 6500 has been prepared for a Build in RIAA module, as an option. P/N 8002956
This 7 pin module has to be soldered onto the BM 6500 mainbaoard. The Mainboard has been prepered for this..

BM5500 has RIAA inside. Same power as BM6500. Missing some powerlink outputs tho.

You might do as follows.
Disconnect and bypass the RIAA inside the BG 6500:
Disconnect the power to the RIAA, then jumper the L & R input on RIAA, and put a jumper to
the output on the RIAA.: You can see the wiring on the RIAA PCB (PCB no 4)
No need to jumper the ground connection. Mute switch is still working.
