Ok, last question (for now)
While playing with the trimmer to adjust the bias, should I be observing Vgs or voltage across Rs?

Voltage across Rs. Bring it up to300mV and let it heat up.

No prob, I just have no clue what you meant.

So, I re-worked one channel and fired it up. offset at 3,5V and bias at 200mV.
I adjusted the bias to 220mV aaaaand my fuse blew. Is 2A slow blow, little? What fuses are you guys using?
I have 230V mains

I ran my with 1A for a while. Did you turn both post equally? Sounds like you were mainly adjusting one pot.

I didn't have enough time until it blew. I turn about 1/4 of a turn one pot and it blew.
I will buy tomorrow more 2A fuses and a couple at 3A to see what will happen.
