I'm sure this has been gone over many times but what the L I'll dive in again.
I am getting a Lightspeed Attenuator and at some point I would like to use it with modified Mc Cormack DNA 0.5 monoblocks which have Lundahl transformers giving them an input impedanc e of 10K ohms. This means I will need a buffer and most of the cicuits I have seen seem to have a pot in them.
My question is, what is the purpose of the pot if the Lightspeed controls the volume and the buffer is to match impedances.
I can solder and I recognize electronic symbols, when I have my book open to the right page, but I would not say that I can understand what values I should have through out a circuit and how it functions.
Ideally I would like to build a straight through buffer with 2 in 1 out and a toggle switch to change between the 2 and if it needs a power supply an on off control.
Simple is better, any ideas?
Thanks Alan.
