I want to White Oak a Phase Linear 400 Series I

That can be from a shorted driver, output, front diff pair in backwards, etc, So.... you've got 120DC on the rails????? AND GET SOME INSULATED MINI GRABBERS!!!!!! Jeez man!!!~ This amp my have been fine before you tested it. I'll post a pic of what the business end of your testleads should look like.
 
Check these out, STOP AND GET SOMETHING LIKE THESE!!!!! It will save you tons of headaches and keep us helping you, by that I mean after awhile, when chasing a problem and by your actions we are getting new ones....it's very difficult, I KNOW!!

BTW ----that was the correct place to check bias. With the amp POWERED DOWN AND POWER SUPPLY CAPS DISCHARGED WITH YOUR DISCHARGING RESISTOR THAT YOU HAVE BUILT ALREADY, (post a pic of that would you), put the neg lead of your meter on the collector bus bar( that woukld be the middle one on each row, and the positive lead on the common point for the emitter resistors. On ohms scale, lowest setting. we are checking for shorted outputs and drivers.
 
SUTTON !!!! SEND EM THE DAMN AMP !!!!!!! L.M.A.O. !!!! Your going to do it or die aint ya pal .
 
Oh no, he started it and he's gonna finish it. Reminds me a lot of me. Kinda like jumping in the water, it's nice to know how to swim, but if ya don't, ya better be a quick learner.
 
So......where are we with this ??? And don't think I'm yellin at ya with all caps, THOSE ARE FOR EMPHASIS!! Does kinda look like yellin. Gotta get through that thick skull of yours somehow.
 
Hey Lee... I went by there last night and Im pretty sure he was leaving for Florida today at some point and time.... LOL... I love the caps.. Your right .... Takes alot to get through that bald thick head of his.... O-Man.... I love him like a brother !!!!! This amp stuff is really getting to him....
 
that's right, I forgot he's gonna be gone for awhile. had some time today so I thought I woulld try to make some progress with him. Thanks Kevin.
 
Ok Mark. He didn't have a service manual. He will now. Will save a lot of redundant posts if he can refer to a service manual. Phase wrote a good manual.
 
Hey guys,

I am still in Florida. I'm scheduled to drive home on Thursday....but we'll see. Don't know how many more times Ill get to see my parents. Their health is really in decline. It is so tough..I ail get a pic of a big resistor for ya Lee...and you are right. The voltages are DEADLY. A Service Manual with all updates really is a must when you think about it. If anyone has a full set, I would gladly pay to get a copy. PM me and I can give you my address and get your PayPal address. It might save a bunch of posts and really dumb questions...
 
Those are good manuals, you just have to know the serial number of your unit or the type of board it has installed because you only get one.
 
Aren't thaw majority of them going to be the second one? The first board is not even replaceable by the White Oak board, is it? Somebody help me with this, because I haven't specified yet...And both versions cover the PL14A right?
 
The first board is replaceable. the ONLY one not replaceable is the fiully comp PL 36.
