If it’s a 1980’s or early 1990’s gold box I’d use that. I’ve tested those boxes and they all retard with RPM. The Gold box only retarded ONE DEGREE in 10,000 RPM. The orange boxes I’ve tested all had 4-6 degrees of retard by 8,000 RPM.

Again, all these boxes retard. So whatever you buy you need to have it tested so you can account for the retard.



This issue with these boxes are manifold, they are ancient technology that while interesting when introduced it has been surpassed. Then there is the issue that the correct power transistor is NS1 and has been for a long time. So whatever you are buying today has something else that may or may not be hacked in with no real engineering done on it.

If you nees the look then consider the FBO setup
