As I said in my first post, I was a bit concerned about the power loss when putting such a high load on the tube (but gaining lower distortion in the trade-off). I ran some numbers tonight and here's .......

I have a pair of LL1620 single ended output transformers gapped for 90mA. I was planning on using these for a single ended 845 project (which they're great for), but they'd also be excellent for a hig .......
