The Phase Linear 400 Guinea Pig

Here's some frequency response on the pig. Used Rev "A" board, 3.5 watts output, 8 ohm load. this one is real good.

UNWEIGHTED setting folks, hard as it can be.

The Pig is no longer in loaner status, the Pig will not leave this house ever again. I don't know what combination made it this way, but it is an incredible sounding amp. Does a respectable 118 db just brushing the 0db mark on the meters, not even close to peggen em. Simply outstanding!!

There will be another loaner in line though.


AND THE RIDICULOUS THING????? Haven't done a thing to the wiring yet, totally stock.....

Now Lee.... You mean to tell me that if I called and said.... Lee, All four of my amps just went up in smoke and im having a big party this weekend that you wouldn't have that Pig on it's way to my house before lunch ??????? LOL !!!! Just always been something about the 400.... It sounds so good and warm.... Really Really GOOD sounding amp. Thats all the amp MOST people need !!! and IF ONE DONT DO THE TRICK GET TWO !!!!!
 
Or get a 700B. But I agree, there is just something about the 400 that is just sweeter, warmer, something. This is not the 400 that had the red hot transformer and had the output of a 700 is it? Man that is a flat FR.

Yes Kev, the pig would be gone before noon. Jani is planning on copying the crossover stuff tonight or tomorrow.
 
Sutton, this is the 400 that got the copper heatsinks. Rail voltage on it was lukewarm----81.5+/-
 
Joe, is the fact the PL has local and global negative feedback due to it's "B" topology or was that a design decision that could have gone the way on the Spec 4. Or can complementary designs NOT take advantage of the local/global difference???

The Spec could have made some choices like Phase did Lee. They could have designed all local feedback loops and no global if they wanted to. Distortion likely would have been higher and damping factor would have been lower had they mades such a choice.
 
So a complementary design is not wed to the sound of a Spec 4 or 2???
 
The Pig has been at Joe's beck and call the last 4 day's. Joe will hit the Spice program and call up a set of changes and on the bench it goes, then back on the AP. Dude's the AP's been runnin HOT!! And soon, very soon we'll let ya in on it.......VERY SUCCESSFUL NIGHT, enjoying the fruits of that also. The Pig went from the test bench to the test listen in 2.48 minutes.............

No sooner than you say you'll stop poking the pig that you go right back to it! :shock: And Joe is prodding you no less! :evil4:

Actually looking forward to what comes of this!
 
keeping us all in suspense

Can't sleep wondering what you two got in the bag!
 
I know we've gone over the announcement date, but Joe keeps improving this thing, and some are incremental and some are huge.....
 
Well, I tried using a hanger queen, and that didn't work out so instead of holding Joe up for a complete rebui;ld out came the Pig, which , the first time I turned my back, heard a snicker, and a faint---( It's about &^%DAMN time..)
