JLCPCB have neither the TPF133A nor the THS7316 3-channel 36 MHz video amplifiers.

They do have the MS1681/, which is a single-channel 36 MHz 6dB amplifier, in a SOT-23-6. We'd need three of them.

The TPD7S019 ESD protection chip is in stock, so I would delete the bypass pads as they are tricky to route so near to the VGA connector.

Or we can buy them from Digikey and offer them as a self-solder part. They have 1300 @ £0.68.

Elecrow were able to find a suitable part.
