Can you post more pictures to see how the Tap Board is being wired? I have ordered one tap board from uk-electronics.
This is the board and I have confirmed with Patreon board for tap tempo. They are matched.
Kit Tap Tempo V2-TA for Digital Delay PT-80
[130-095]
The rail is the connector for tap tempo board, isn't it?
I see how the Jumper resistors are connected. So, leave the JUMP label off and Wire the TAP with 0 Ohm resistors.
