Hey SuperG apologies if this is a basic question but I’m having a slight bit of trouble.
I have a modded snes JR with this amp

I also have 2 scart cables, one csync 470 ohm and one csync Ttl passtgrough from retrogamingcables.co.uk
The std cable:

Packapunch(fully shielded):

Retrogamingcables checked the mod I had installed and advised to get the ttl pass through version of the pack punch: That board is supplied as 75 ohms impedance as default, which means that they have the 470 ohm or similar value resistor installed on the board, therefore you need our cable wired for TTL, which is a pass-though. If the board was set to TTL, then this would mean that our cable would need the 470 ohm resistor inside the AV plug.
When I use the csync with ttl passtgrough plugged into the pvm the snes works but when I plug it into the gscart switch lite it says soemthing about sync signal not strong enough, anyway it screen then stays blank.
I tested the csync 470 ohm version in the gscart and that one works.
Obviously my preference is to use the fully shielded cable.
Any idea what’s going on here?
