Hi Pete,

I am in the process of repairing an old classic of mine. The Hafler DH-110. Like many I am having issues with the J112 switching FET. Yes, I could just replace it when it fails but I would prefer a better more permanent solution. I would like to eliminate the J112 and modify the circuit with a high quality relay. I have read from a really old post that you have done this mod. If you don't mind would you care to share how you did it. I did not see a post anywhere on this. I studied the circuit but I am not seeing how do do it even though it looks like a simple solution. You can send me an email as well.
