I have a Magnecord PT6-J unit that I would like to remake into a Federal Limiter. The output transformer looks like it will work with a 10kct primary and a balanced 600 ohm tap on the output. I plan to use an Edcor XSM 600:10K on the input (its fits right in where the EQ network module was so I can use the shield and overcome some of the Edcor's shortcomings there. My main concern is the power transformer has way more voltage than necessary. The power transformer is 700vct and has a 5Y3 for a rectifier which is on the orignal circuit, but I only need half that voltage for the Federal. I plan on adding a Hammond 158L Choke for smoothing, but what is the best way for me to knock down the voltage and is it even necessary? Can I run the limiter at a higher voltage? It looks like all the tubes can handle it, so what problems will I face running the circuit with higher voltage? Is it just as simple as doing the math and knocking down the voltage with a big resistor if need be? Will this effect the limiting capability in a negative way?
