Anthony,
as you know Croft preamps use dual-mono pots, so I guess that DACT would offer something similar. Is there is a specific model that you would recommend? Is it a drop-in replacements to the existing TOCOS pots? Any idea about the cost perhaps?
Thanks
Panos

To be honest, the dual pots actually play the role of a balance pots. So I would not like to eliminate them and substitute them with a single stereo pots -))

Hi
I also use the Khizmo 50k series pot in my dcb1 turbo and would concur with Oliver.
The transparency and bass authority is by far the best I've heard.

I'd drop Glenn a message and ask him if he could help you out.

I don't understand, why is no one recommending the Khozmo Ladder stepped attenuators?
Is it just cost, they are 40 t0 50% more expensive than the Shunt or Series, as you need 96 resistors per channel, not 48/49.
The problem with the Shunt has been explained, you have different impedance for every setting.
For me the problem with the Series type, is just that, you have 48 resistors in series with the output seeing the number of resistors dictated by the rotary control position and the remaining number going to ground, the sum of the two equaling 48. At low volume there will be many resistors in series for the signal path, is this not a bad thing?
Surely the Ladder type is the best, where you have pairs of resistors for each volume position, one for the signal and one (matched) to maintain impedance. There is only ever one resistor in the signal path and constant impedance is maintained across the controls range.
The only difference is that the Series uses multiples of resistors for each value, the Ladder uses a single resistor.
I would have thought the Ladder was the better choice?
You still get +/- 0.1dB channel matching if you want a stereo version.
So why not the Ladder?
