The Amp Garage

Adding a grid stop resistor at the input of the cathodyne phase inverter gets rid of the nastiness when the amp is cranked. I built a 5e7 style amp and added the grid stopper and it sounds great when cranked. Tweed overdrive without the nasties.

You never know unless you try. One of my pet peeves is people telling other people "it won't work", "you won't be able to make it" etc. etc.
Go about it smartly & give it a try.

Hi,
I'm new to this forum and was wondering what the ratio control on dumble amps is for?
Thanks
