Title: RGB on a US Duo vs a US TG-16???
Post by: ConHuevos on September 12, 2015, 02:36:02 PM

Got a question regarding the video out on a US Turbo duo.  I recently switched from component to RGB and modded both my TG-16 and my Duo.  I grabbed RGB and Sync from the 6260 and sync is being amplified through a LM1881.  I'm using the RGB amp that has the THS7314 with the 3M pullups.

It looks absolutely great on my TG-16 but my Turbo Duo has some blurriness to it and it's very noticable.  I double checked everything and it's exactly the same setup.  Is this a known thing?  Thanks.

Anyone out there that could confirm or deny this please?  Thanks.

what ground/ grounds are you using? For both the RGB amp and the Scart cable in your DUO.

The amp is getting the video ground from the 6260.  I replaced the stock DIN 5 with a DIN 8 and it's getting the ground from the PCB ground plane from one of the DIN 8 through holes.

So you have both the ground pin for the DIN and ground plain wired up to the scart cable? This is correct but make sure to not meld them together when doing RGB. Meaning the din 8 ground pin should go the the ground pins for the scart cable. The outer ground plain ground should only go to the outer ground sheild for the scart end.

Not sure if you have it wired this way or not.
