Jeff, I'm not familiar with this situation. Are you saying that having the CRT modules disconnected when running the set will cause the convergance chips to blow? How about on a CTC178 chassis, will the same thing happen? The CTC178 I've been working on has been fired up without the CRT boards on. The vertical ouput IC smoked but I haven't found out why yet. I hope I don't have any convergance damage besides. (I only work on this set when caught up with other work). Thanks.
