If you have $14,000.00 to spend, the best remote control preamp (ever) should be available in less than three months. Not yet public, but I assure you, worth the wait, if within your budget.
I will call and find out if he is any closer to making this a reality and if he is willing to let me post the info.
The difficulty is in using only a discrete ladder bridge with precision mechanical switches. This makes building something to "move" this control the issue.
If it was a TKD film pot or digital it would be easy.
