Now that I've gotten my CTC-9 up and running pretty well, my thoughts have already turned to improvements in the circuit. DC resto comes to mind first, so I did some searching. Turns out there's an IC (LM2480 triple bias clamp) which will serve this purpose, but I have no idea if it could be adapted to my set. Problem lies in the fact that the IC does DC resto at the CRT cathode, where my CTC-9 drives the grids. So the question then becomes: is it possible to use a device like this on my set, or would the conventional diode setup still be the best choice?

I never got this in depth with TV's before, so I'm gonna need some guidance on this one. Replacing caps and general troubleshooting I'm fine with, but I have no idea how modding the chassis in this way would turn out.
