Re: DR7 fitting partial success.
That¡¯s the term I was looking for, fish paper. Drake may not have widely implemented that ECO but I have had several TR7¡¯s that did have it and I installed it on every one that came through here.

Re: DR7 fitting partial success.
Hi Mike, The loose left wire is for segment F. The center wire is for segment A. The right wire is for segment B. Suggest re-soldering all three wires. You can use an ohmmeter to check for continuity

Hi Roger Thanks for that, I just checked and looking at the board from the front, there is a bad solder joint on the left wire link of the three. Just resoldered it, it came off in my hand. Fitting

Re: DR7 fitting partial success.
Hahaha I bought a blue Triumph TR7 like that but a hard top in 1985 with my ill gotten gains from my first job overseas AND I bought a Drake B line. The previous owner had upgraded to a Drake TR7 73
