SpeedRacer![]() | Re: Protecting Output tranny Couple of basic things that can help: 1. Fuse the CT 2. Build a spark-gap in the plate circuit 3. Put a 250-ohm 5W resistor across the outputs (or across any of the taps - eg: 0-8 or 0-16 etc) This should cover most any disaster short of your using an OT that is out of it's depth WRT current flow in the output circuit. In fact nos 2 & 3 are redundant, but I thought i'd toss 'em both out and you can do what you like. Spark gaps are cool. ![]() |
