    My BU931T transistors arrived today from HongKong, about $12 Aust for 10 freight free. Testing it on my test unit they work fine upto about 2000 RPM then stop sparking until you drop the RPM. If you add the Mosorb in the original circuit they work fine at higher RPM, My unit only goes up to 3000RPM. So they should be fine so long as theres a protector used.

    Now that’s interesting..

    Do you have any sense as to why the Mosorb raises the upper speed limit (essentially, gives you more HF bandwidth)? At the moment, I can’t think of any possible mechanism, other than some device-specific quirk.

    Electronics can do the craziest things.
