Kinda like the guy in the corner of the boxing ring eh?? OK here we go...

Yeah, I am the cut man...

 

[laatsch55]

OK, clips at 387 into 4 ohms with rail voltage at 79.7.... What's up with that Joe....

You thought you would never hit the SOA protection Lee?

Are you looking at your 79.7V with the scope or are you looking at the RMS value with a DMM.

 

[laatsch55]

Yeah, I am the cut man...

And a legendary one at that.......around here anyway...

The Fluke 179, set on DC volts...

 

[laatsch55]

So, you're saying the 1304 and 5's are in play...?

That is giving you an RMS reading Lee. It may be drooping terribly on a cycle by cycle basis. You should check.

Can very well be Lee...

Ok, how do I set up the scope??

 

[laatsch55]

Should monitor incoming mains then too...

 

[Gepetto]

Ok, how do I set up the scope??

Synch channel 1 on the output signal and then put channel 2 on the B+ test point on the backplane board and look at it at the point that the signal starts to clip.

This is a stock 700 Joe....

 

[laatsch55]

With RCA 410's and XPL-909's throughout....

 

[Skynyrd77]

Hey look I got a thread!!!

 

[laatsch55]

Um....YEP....

 

[Skynyrd77]

And in SKYNYRD English that translates to
FUCK YES!! FINALLY I HAVE A THREAD FOR A 1000 WOPL!!

Ooops thought this was a converted one. Then just look at the B+ collector rail on the channel you are measuring. And don't blow it up.

 

[Northwinds]

I love where this is heading hehehehehehehee

With the scope in DC coupling? And don't blow it up??? Dude that's why we are doing this, to see where it goes south at 4 ohms...

 

[laatsch55]

And we have 10 amp rail fuses and a 15 amp mains in fuse installed....
