Applying a SUS control in a SE Amp with a Master Volume
#1
I'm trying to figure out the best way to apply a SUS control to a cathode biased SE amp I'm building.  Overall the topology will be similar to Blackface Champ but it will have Power Scaling and I'd like to add a SUS control.  For the limit control I was planning on adding a Master Volume before the grid stopper of the power tube.  Can the SUS circuit connect where the Master Volume pot usually grounds or is it better to have it work off a grid leak resistor after the master volume control?  Thanks for the help!
