Reasonable price for a PL 4000 ii

[Schmurpy]

What is a reasonable price to pay for a great looking PL 4000 ii?

Are you sure you want to do that?

 

[Schmurpy]

Lol, do what; ask the question, or pursue a PL 4000 II?

Ask Perry, he will have some opinions on this. The 4000s are pretty women, look great, high maintenance, so-so engineering.

Get a carver c4000 or better a carver 4000t. They match well with the phase linear.

Yup, you won't regret it...

Although I've heard a lot of flack about the 4000/II, I have to say that mine has been trouble free until recently, left channel dropout with autocorrelator engaged. A lot has to do with the internal architecture, backplane with daughtercards. The trouble comes from the card slots and ancient (sometimes sloppy...) soldering. They crack!

I think they're good overall, but what you may get will be "iffy" as to proper functioning from those issues. Even if you get a good one, with time it may crap out. I lucked out on mine! But by ALL means, STAY AWAY FROM THE ONES WITH THE JOYSTICK!

The C4000 improved the PL4000 by using dual power rails, plus and minus. The PL4000 has a single rail so every stage has to be capacitively coupled to the next. A lot of complexity and overall lower performance. They used a lot of electrolytics for that coupling which do not age well.

Although I have a PL4000, it sits on the shelf and looks pretty.

Details that I didn’t know...

 

[grapplesaw]

series ll 4000 is dual rail


I need to clear up that the series one 4000 is a single rail supply
the series two 4000 has dual rail
please see partial schematic attached

 

[grapplesaw]

So to go a little further on the series ll 4000
its bells and whistles do not quite a match the Carvet c-4000 or Carver 4000t. The rest is pretty good. I have a PL4000-ll
sitting to be reworked and will have updated power supply, electrolytic caps changed out, new opamps , added new remote volume control and remote on/off so it can also remotely switch a pl400 safely.

 

[mlucitt]

new remote volume control and remote on/off

Let us know which one you choose, there is a dizzying array of Chinese remote board kits out there.

But the one with the joystick is so damn pretty! Lol....

Yup, the siren's song...
