LDR Lighter Note Passive Preamplifier
 
3 Attachment(s)
I built this Lighter Note passive preamp for myself. I tested it on my system and decided that I need a linestage with gain.

Preamplifier uses light dependent resistors to control attenuation, keeping sound signal free of noise and other mechanical "distortions" introduced by mechanical volume pots. The preamp can be adjusted to desired impedance, tailoring it to your particular system needs. It has two pairs of switchable inputs and one pair of outputs.
As you can see in the pics I used premium RCA connectors, silver wire and put everything in a rather expensive aluminum chassis.


Asking $385 plus shipping and PayPal fees.
This one is SOLD.
