LJM L25D volume control

[ALMIGHTY]

Hi.
Did anyone build volume control for l25d amp?
Are 50k LOG pots ok?
Does anybody have schematic for volume control?
I am new to this,so can somebody help me?
Thanks

If its like the 2092 amp it has a low input impedance.
A 4k7 should be about right.

The low impedance can be fixed with a input buffer.

And how do i do that?tekko

A input buffer is simply an opamp with the output and inverting input connected together. This is also called a unity gain amplifier.

How does it work with the 5K log pot?
