Not really to be honest. The PH 9.0 took over priority, at the < $3K all tube design range.
In the interest of efficiency, I could see possibly using the same base enclosure for the $1K model but with a simpler face plate and controls. If so, it would be 10"Wx10"Dx4"H. PS may or may not be external, depending on how quiet I can make it.
Thanks,
