LOL.....I am sure all of us have done this at least once! LOL
Why would one care though if it is the worlds smallest echo board?
Radios are getting smaller; try adding a big echo board and any other accessoryWhy would one care though if it is the worlds smallest echo board?
Still have them could you pm them to me?BB-3 BB-2
Ive got them for the bb-3 and bb-2 if that would help. they got to be close to one.
Sonoma the bb2 has a loose yellow wire next to the power wired for the board as well as a loose red wire on the potentiometer for echo control maybe it's used to break power to the board not sure but it's not the same as the l2n you posted I had some of those to they are easy to hook uphere is a link to one on ebay that you can read how to hook it up. basically the same as what you are wanting to install.
