Hey Guys,
I was the hold up on this one, getting a schematic to Cliff.
Now I can only speak for the actual amp, but my preference of speaker is a Celestion Creamback 65, though I gig these regularly with a 2x12 with Celestion T75's. Its pretty forgiving on speakers compared with some models.
The foot controller and bias monitor are two of the wonderful features of the actual amp, but are both moot in the model......unless Cliff wants to model the effects of real world mains power fluctuations from place to place, but the 'green zone' of the bias monitor is 62-65% plate idle dissipation power and it measures and compensates for plate voltage and screen power , which means the real amp runs best at a slightly cooler bias. The bias monitor just allows you to set that consistently from venue to venue regardless of the main power.
