Default Looking for KT88 Amplifier Schematic by Mikael Abdellah

I've been reading in the forums about a KT88 amplifier schematic from a Mikael Abdellah. He posts a link but it's gone dead.

Does anyone have a copy that they could post here? Really curious to see what it looks like.

Thanks for the help.

What kind of Power out does the circuit offer in Triode, and UL modes?

Ah... deep dish is on the menu for tomorrow evening. Though I have to say that right now you might not miss it so much when you realize we went from 79 degrees on Tuesday afternoon to a high in the 30's yesterday! Plus there are only the two seasons here- winter and road construction.

I haven't measured it in triode but in UL I measured about 7.5 watts into a 5K James OPT with an 8 ohm load. My voltage and current are a bit higher than Mikael's schematic specs. I'm at about 424V B+ and 82mA on the KT88.
