    Phase linear 4000. Worth the recap?

    Picked up this phase linear 4000 preamp a while ago. I got no sound out of it. I assumed it had cold solders and put it away for a while. Looking through my stuff for things to sell to thin the heard, I came across it again. I figured I’d give it another shot. Hooked it all up and messed with...

    Phase Linear Dual 500II opinions

    Hello, I feel very fortunate to have this Monster Power amp in my collection. It stays in the Garage because it's just too much power in the living room. Pair that with a lack of restraint on a Saturday night after Midnight and well, you've got neighbors knocking on the door asking WTF...
