/diy/ - Do It Yourself

I just posted this in qtddtot but figured I'd post here too.
I'm trying to build pic related but I don't fully understand plate-transformer-output impedence matching. I have 60ohm headphones and since I don't use speakers I wanted to change the output (from 8 or 4 ohms) to something useable. I know I need a different output transformer but I don't know how to look for what I need. Should I just build it first to make sure it works and then focus on transforming it to a headphone amp?

That's a link to the build if you want to look at the whole thing.
