Google finds several out there, but none for the GT4 that I could find. Here’s a thread I commented in.
Id like to find out if Id need to refocus the GT4 reflector before proceeding, which is sometimes the case after dedoming or HI swaps. That for me has always been the frustrating part of surgery!
Agreed! The GT4 should still created one hell of a flood beam with 70.3 HI emitters.
Oh, and thanks again for all the hard work you and others have done in bringing this monster to fruition. I hope yours still gets some good use!
