I absolutely love it!!!! but I need some help to be honest. I have 2 questions that I hope the experts here can answer.
For context: I have recapped the power supply and cleaned all the connectors. I also put 470hm 0.6W Resistors on 3 of the output lines since I saw online that it should bring the TTL sync down to 75 ohm. The reason for this is because I wanted to output to my PVM and to my retrotink 4k simultaneously. I already had a bnc to scart converter on hand, so I figured it would be better for me to just put the resistor in the Extron rather buy a bnc to VGA cable.
1. Regarding the 470ohm resistor mod are the readings I am getting actually 75 ohm sync? I am using an RCA Y adapter to send it to both the PVM and the scope at the same time, so it get terminated. I don't know exactly what it is supposed to be, but I can't help but feel like something is off here:

Video of sound: (for some reason I feel like youtube lowers the volume on shorts automatically this is actually very loud) edit on this issue:
I have done a little bit of testing. If I plug just the Red, Green, Blue, and H sync board in I get no hissing at all and it boots up instantly.
If I plug in any other boards or only plug in only one of each of those boards I get the hiss, but for some reason those 4 boards together work fine.
Thank you in advance to anyone who takes their time to reply.
