What type of volume control is in the XP10?
DS1802 like in INT-150?

Not saying at this time.

Oh, than I have to commission James Bond to investigate...

He will gain insight and we will than build an XP 007.

Does anyone knows more details about "Wayne Colburn's exceptional volume control" in the XP-10?

Anyone opened the case?

Is it the DS1802?

Please don't answer: Buy one

(they want 6000€ in Germany, about 10.000 US$!)

Assuming we're talking about the same thing, Wayne's circuit is discrete and patent pending. You'll be waiting for a while.

The electronic volume control allows greater than 70 dB range and is driven by a micro-controller that reads the optical encoder serving as a front panel volume control. In this manner tracking of the volume of the two balanced channels is possible with accuracy unavailable on any ordinary volume control, assuring precise level steps and high common mode rejection in balanced circuits. Wayne Colburn’s exceptional volume control in conjunction with the fluorescent display give the user ability to replicate volume levels with absolute accuracy in steps of roughly 1 dB.

I think he is using a chip for attenuation and this chip will be free available. I don't think the circuit around this chip is patent pending.

You are talking about two different volume controls, one discrete, another
a chip set.
