Exchanging the crystals PAL <-> NTSC is only required if you need exact timing (100% video compatibility, genlocking, VCR, ...). I can't imagine monitors/TVs to be picky on this.

For RGB that is. If you're trying to use a composite or Y/C signal, the crystals will have to be swapped (plus the video encoders).

The A500+ service manual just states "GND" for pin 41...

btw: "8375" by itself does not really say which Agnus type it is. There are 1MB types (A500/2000), 2 MB types (A500+/600) and even (rare) 2 MB types for A3000, so a "8375" can just about be any ECS Agnus. The two latter 2 MBs are NOT compatible...
